Honestly purchasing used parts was a stroke of genius! I was all ready for you to recycle the broken motor, and get a cheap harbor freight. An update to my riding mower, I decided to spend the money for a new motor. It was in and out of shops last summer more than it was actually used, so the old motor is going to a local kid that likes messing with small engines in return for installation of my new mower and a very beat up riding mower with a good motor that came with the house. It frees up space in my garage, and I get free labor, a win-win in my book.
I hit a small hiddden stump with my Honda lawnmower a few years ago, bent the crankshaft pretty good. I pulled the whole motor down and ordered all new OEM parts along with new cam gear and belt as just in case parts since I was already into the engine. The parts were actually very cheap, took maybe 4 hours to put everything back together. Honda use gray RTV sealant as the crankcase gasket too but I used a technique I saw on another small engine repair channel. Basically a very thin bead on both surfaces and tapping over with a finger tip to create even small peaks of texture on both surfaces. Letting it set for 30 minutes to skin over then fully assembling the halves. Looks much more professional, uses less sealant, and zero leaks.
I agree with every decision you made. You took a non runing destroyed engine and got it running again. Yeah you bought used parts but they were in great shape. You good Sir have patience that i only dream of having. Cant wait for the follow up videos on this mower. Great job again with this repair
@@HomeGaragechannel Great story you told with the cost analysis. Reminds me of stories of how we won the war in the south Pacific in a class for "Operations Management" for engineering😄. Most money went to the ETO (European Theater of Operations). Heard stories too from veterans
Great video. I think it worked out great. I'm in a similar dilemma. I got a free 550ex edger and the motor is shot. I'll be purchasing a $25 used mower and doing a motor swap that's less involved. I'm sure if you would found a $25 mower engine you would've done the same but cheap mowers and free mowers are getting scarce. Your knowledge of motors is amazing. Keep up the great videos.🎉
Good video sir! I just recycled a quantum Briggs; it's previous owner let the black tar inside the engine run very low. Disassembly was surprising, Crankshaft and conn. rod were fine, the piston and rings scarred ONE side of the cylinder nearly seized). I pulled a good piston with rings and block- both used- and reassembled. She is back in service! BTW, I have not bought a sump gasket forever- I use Yamabond. Never a leak.
With working with my neglected craftsman m210 was been fun frustrating all of that the story behind it is my dad bought it back in 2019 and was stored in a really crappie shed the handle rusted and the self propelled cable broke this year nothing had been done to it the bottom of it had never been clean and the oil hadn't been checked for a long time and the oil was low when I started taking care of it
The blade was half of the size it should have been I changed the oil and replaced the blade but I over filled the oil and it made a big mess and to top it all of the carburetor got so used to the neglect it killed its self then I had to get a new carburetor then I pressure washed the bottom to find barley any pain and rush then when I say I'm finally done with finding bad parts then I look at the belt and that's wore out stay turned for more on my channel.
Being on SS ( no small irony that its the same acronym as the WW II folks) I applaud your approach. Sure the compression release was a faux pas, though its a learning experience. Once you silicone seal the valve cover gasket, you'll have a nice little mower. How about a piece of velcro for the stop bail :)) Love your knowledge and videos.
I hit a rock with my fancy self propel husqvarna mower with a Briggs engine and bent the crankshaft. Ordered new crankshaft and gaskets. Put it together and it knocked. Bad connecting rod. Took it apart again and put in a new rod, new crankcase gasket again, new oil seals, new valve cover gasket. Was putting the head on and over torqued it, snapping a head bolt. Ordered 4 new bolts and reassembled again. It fired right up. Hoping it stays working bwcuase it was a pain in the rear and a lot of money but I like that mower lol
AMAZING how an owner can screw up a brand new machine due to something as simple as not adding oil. Great vid. Real world scenario would be to junkit. Love the passion and knowledge here man!! 😊
you may not have gone about it the way i would have but i cant argue with the results it runs way better then i expected it to and you did make a good point its just a lawn mower engine worth $200 also RTV gasket maker i used it on the timing cover of an engine i rebuilt and it works just fine RTV is only an issue when extreme amounts are used and a piece breaks off in the oil pan and finds its way into the oil pump pickup
Outstanding work!! That's what I would have done . Now if it had been my personal mower I would have gone with a new engine with the price of mowers now a days that would have been cheaper. But with what you did who ever buys the mower will have a number of good years of mowing with out spending alot of money well as long as they take care of it.
I've ALWAYS loved Craftsman tools but never their mowers. I had a Craftsman riding mower 20yrs ago. My yard was sloped, hence, I blew a rod because oil wasn't getting to correct parts. Was THIS mower from a hilly yard? I have NO PROBLEM on how u handled this rebuild. U are very knowledgable. NOW, if u treated a Honda in this manner, I'd have issues. Great rebuild! And thank u! 👍🇺🇸
I agree with everything you did besides the sump gasket. We have actually used the copper spray on a gm 604 crate race motor (425hp) head gaskets. I have rebuilt an old flat head briggs and its worked for a year before metal was found in the oil. (I used assembly lube breakin oil, and then used small engine oil). So here in a few weeks my grandfather and l are going to tear it apart and try to fix it again. I have a complete nearly identical used motor at my disposal, so we ought to get one of them running.
I like the way you work. It’s a shame you have to constantly say that people may not like the way you are doing it, but you are right. People on UA-cam are too quick to cry about how you are doing something “wrong” when cowardly hiding behind their keyboard.
Was all this worth it? I say “yes”. You learned a lot more than if it had just been a carb clean and pull rope replacement. That knowledge is now permanently yours to draw from. That makes it valuable and worth the experiment. It will save you lots of time going forward on other mowers.
I think if you take a chance you'll give it a try that's all. You can do nobody knows if it's right or wrong at the time. I think you don't know Unless you try That's all you can do You did awesome job Thank you for the video
Good job! I would do the same thing with the sump. BUT, I usually don't bother rebuilding even with used parts. I'll get a good engine on a crusted out deck at some point - or convert a pressure washer engine with a deep blade adapter if needed. I would have no qualms selling this as a good, used mower if I were in your shoes.
Yes, it's only a lawnmower so it doesn't matter but I bought a new crankcase gasket for it because it's the standard 0.15 millimetre thick gasket which maintains the correct amount of crankshaft end float. I only spent $50 AUD on parts in late 2019 on my old 1988 model 3 horsepower L headed Briggs & Stratton lawnmower engine which included new piston rings as well,I reused the original 31 year old cylinder head gasket as well. I did hone the cylinder out as well although they all say that you're not supposed to,it does blow a puff of smoke when first starting the engine but it doesn't use very much oil now & the spark plug runs grey now instead of black & oily like it used to. I don't have a problem with how you did it because I probably would've done the same thing !
Very interesting and educational. Its obvious you really know your stuff. I would have bought/found a used motor and re-powered the deck with it but that wouldnt have made for as good of a video.
@@HomeGaragechannel Yes sir I'm still trying to figure out why they dumped it🤔 Took it home changed oil sharpened blade through in a clean filter and she's been running every since✔️
It was a good idea to buy a used piston and rod. I would have done the same exact thing but I would have bought some new piston rings, that is the only difference. Keep up the good work. 😊👍🏿 #stihlpower #stihlisyourdaddy #stihlrunstheyard
Instead of a string, I use the large reusable twist ties HD and Lowes carry for cables and hoses. Keep them on my equipment to hold the deadman to run the fuel out after the fuel valve isclosed.
I found this video very interesting even though I would not have rebuilt the engine. I would just find a used complete engine. I have successfully resealed a sump but never tried the copper spray for the head gasket.
I don't tear into engines at all too time consuming . I have a couple of motors kicking around because the decks are usually the first to go so I would have but one of those on instead ! I would change the cam out though ?
I've used the copper coat spray for years, works great on low performance engines. Nothing wrong with gasket maker - most of the time an engine like this will never again be worked on.
Use for spare parts. I had a good chuckle about how you had fun with engine because somebody had to have a go and it makes great entertainment. Hopefully no one will try this on a decent engine ??? Go to Pakistan and see how they rebuild crashed vehicles.
This was still a great learning experience for all of us, and I appreciate your reflections on the mistakes you made and how you could have done it differently. No problem with used parts, as long as they are in good condition and it is within reason/safety. I've had to use copper spray for exhaust gaskets (in good condition) on the connections between exhaust pipe flanges and had no issues. As for the gasket maker/sealer, it has become commonplace for automotive manufacturers to use that instead of an oil pan gasket on newer vehicles. As long as it is compatible with engine oil, I don't foresee you having any problems using it. Did you know that some newer Honda small engines use a timing belt?! Supposedly, they are designed to last the "lifetime of the engine" which I guess means when it breaks, everything else breaks? 🤷♂ I live too far out from any nearby towns, the roundtrip alone is easily an hour or an hour or more, so I always have to make the decision to make a separate trip for one or two items or wait for the next day and get it after work (if it is available in town). It is even worse on the weekend. This has led to some...creative...other ways to get certain things done. I look forward to the performance results after it gets some working time in. Saved another one from going to an early gra... landfill! 🐺🔧
all honda OHC engines use oil bathed timing belts i've seem them last 2500hrs and i've seen one snap but due to all honda air cooled engines being non-interference engines valves do not open into area where the piston travels they just sputter to a holt new belt and back in business
thank you Jonathan Sherwood, I appreciate that. And yes the timing belt is bathed in oil. The interesting part, is that I've never had one of these, with a broken belt, even the neglected ones.
Good video! I find myself weighing out the cost compaired to what I might make selling the equipment. I have a Cub Cadet electric start walk behind mower with a rod knock. I am looking for a used mower with the same sized engine to swap. I will hang onto the mower as it looks like new. I will not be breaking any engine down like you did. The labor involved for any shop would be enough to convince anyone that it wouldn't be worth fixing that mower and it would end up in a scrap pile.
on my lawn mower if I pull the "safety bar?" and then try to manually spin the blade it gives a bit of a groan and seems like it needs to be oiled, or in other words it seems like it has difficulty spinning freely. I was just wondering if this is normal? I have tried to put oil at the base of the blade's axle but it doesn't seem to have helped much. what would you recommend I do for this?
Could you gasket problem be solved with a gasket kit? I had one where Just the head gasket was $8 but a full kit was $13. And I needed the sump gasket anyway. The remaining unused gaskets are in the sleeve they were mailed in, in my garage filing cabinet.
I have a Toro super recycler that i bought last year that, even after 2 months of ownership, oil started leaking out of the same valve cover gasket. The engine is practically the same as that one, but probably a little bit bigger. Theres a huge design flaw with those OHV gaskets or the cover as it has a habit of crushing the gasket when you tighten the screws rather than just tightly seal. And heaven forbid you open it when it is warm cause then you need to wait for the damn gasket to cool to shrink back. I ended up replacing the original gasket with a new one and even after using the new one for 3-4 weeks, it too had started to leak oil from there again. I was seriously fed up as it was a new purchase. But eventually it seems like either the rubber melted to the right shape for a proper seal or the dust after me dethatching created a scab of sorts around the OHV crevasse as it hasn't leaked out oil since last year thankfully.
thank you for the information, and yes it would seem it's some sort of design issue. The strange part is that I've seen this gasket in either rubber form, or as a rigid thick paper gasket. If I had to replace it, I'd like to choose the rigid one, instead of the rubbery one.
@@HomeGaragechannel The one I have on mine is rubber. I've always found it so odd that it isn't more stiff. Is is very flexible and maliable and it does not enjoy being removed and put back. Also tears very easily too as I found when it stretches during operation internally, it seems like it rubs against the threads of the screws as my first one developed a tear after just reinstalling it a couple of times. I ended up purchasing a pack of 3 of them and luckily the new one ceased having issues. But if I ever have it happen again, I will just go with a stiff one. I also feel like the oil runs up the threads of the screws as well when it thins out when hot as the threads on mine were always covered in oil as well. Always the bottom most one too.
Remember the engine I was talking about that wouldn't turn? It would make 1/16 of a turn then make a thunk and stop. Turns out the rings gouged out the cylinder. I'm still going to try to run it with only one ring, but it's not gonna be pretty!
I was sitting here nodding YES all through this video. I MIGHT have got a new piston and rod BUT maybe not and I use a LOT of 2nd hand Ebay stuff. I just have to try and be careful to get what I need and if I have a question I always contact the seller. Gaskets? I'd reuse the head gasket and lay the #2 to the sump. I've done that more than once too with no leaks. Torque wrenches? I have a walking beam and a micrometer that will go to 250# but with head bolts it's usually an 8 inch combo box and pull the bolts 3 or 4 times after oiling them up first. I pull a head a lot tighter than factory and anti-sieze the threads but have never had any trouble with any stripping, breaking or backing off. And as far as cranking, if the rope is running around the outside of the pulley, THERE is where the most pulling power is and easiest starting. Waiting on the next one and Happy Weekend!
@@HomeGaragechannel Some of the commentors, probably the biggest part have NOT walked in YOUR shoes and mine are too big and stinky for most to mess with. It's easy to run ones mouth out of an armchair.
Great video! I have a question for you, I have a stihl fs90r and it idles good but will not rev up and the head does not spin, what do you think it could be?
hmm. now they may be the same issue. Without the engine speed changing much the clutch may not be spinning fast enough to engage. So I'd work on the engine issue first. have you looked at the spark arrestor screen for a clog?
I would remove the muffler and check the exhaust port, on the engine. The port could be blocked there. Then I would start and run it without the muffler and see if it still does it then. If it's still doing it, then the carb needs to be adjusted or serviced
I had a box of parts off of scrap briggs flat heads. i was putting together a vertical shaft 4.5 hp block. i didn’t have rings. so i used a piston and rings out of a horizontal 5hp made in 73. swapped wrist pins out and they fit perfectly. permatexed all gaskets accept head gasket. valves out of idk what. rusted gas tank. threw on a mower deck and it’s been running no problem for 3 years. sure i have a better mower. but seeing it run for so long is crazy.
@@HomeGaragechannel yea it always fun to scrap something together and see how far you can go with it. let it sit outside all winter with old gas. i just went out and 3 primes on the carb and it started 1st pull.😂
The problem is a lot of these newer Briggs & Strattons are putting things like “never change”. Of course average consumers fall for it and this happens.
I would have done everything you did apart from (1) a new head gasket (2) a used cam shaft with compression release (3) a new valve cover gasket. Everything else you did, I have no issues with.
I think you did a great job. It's hard to spend top dollar on something if its not going to be worth it. If I were keeping it for myself I would definitely follow your ideas on repairs. If I were to sell it I might hesitate. It would suck for it to fall apart after selling it if the repairs didn't hold. The main thing that kept coming up in my mind is how cheap engine manufacturers have become. So much plastic all the way down to the camshaft. Then they have the nerve to sell those mowers for top dollar.
@@HomeGaragechannelI watched my Dad do it in his shop for years and he allway did it on lawnmower engines, I only seen him buy a few new gaskets in all those years
This was a good fix. I would've either taken the route you did, or more likely, waited for a free mower with a rusted deck to come up and just do an engine swap. But that wouldn't make for as interesting a video.
I was a backyard auto mechinic. My family would on a weekend - pull/disassemble/get parts ( 30 miles away ) /put back together in a weekend.. this is my thoughts - if you had such a catastrophic failure, buy a new or used engine. why - the possiblity of metal in the oil pathways. I do not know what is on a lawmower engine but they run through the whole engine of a car. If I was to keep instead of sale - I would cross my fingers. but to sell and risk a return - for me - no. - so tell me - are there real oil lines like a car engine - or something else that would not hide loose metal.
what is with all the haters in the comments? good Lord it’s a lawnmower, not a small block 350! I think what you did was smart, breathe life into a old machine.
I have a 3D printer which I understand most wouldn’t. But I totally would have tried to print that valve cover gasket from tpu if I couldn’t get it to reseal.
The only real difference in what I would have done is to replace the camshaft in the first place. When a part like the compression release is broken, I have to remember that the engineers would not have spent the money to have it if it wasn’t needed. I’ve been down similar roads too many times.
Hey bro, what's up? I honestly don't mind spending my money to get my equipment running properly again. However I weigh the pros and cons in order to get my equipment running again. If my cons outweigh my pros well that's the route I'm going and vice versa.
Reusing the head gasket... these aren't Formula One engines. They work quite well with minimal care. When I raced go-karts, every week I would remove the head, and re-set the valve lash. I did NOT replace the head gasket every week. But I WOULD find a way to put the compression release back in. Used cam or new. The cheapest one you could find. Repairing this engine, I would have gone cheap route like you did if I had access to the used parts.
If you're going to sell a repaired unit, it pays to do it tge preferred way, since a come-back would cost you even more $. New gaskets are a good idea.
I liked your experiment regardless. Is this engine worth fixing? No, to me it isn't worth purchasing brand new on a piece of equipment. I would sooner go for a PowerMore engine over one of these, and in fact, I have, at least once on a Cub snow blower. I also had experience with one on an MTD made mower and it seemed to be a reliable little engine.
i've been trying to sell a rider in good working condition for $300 , but had no calls . it seems insane that a pushmower can cost $500 . modern times .
I did not see you do anything to the crank journal this all kinds of scrapes and gouges on that that you should have taken off before putting the connecting rod back on it's going to transfer to the connecting rod and then freeze up.
So the crank journal was in pretty good shape, surprisingly. There was no aluminum on it from the rod and if there was I would have take it out to polish it, but it wasn't needed this time. So no freezing up here.
I really like your channel and i agree with most of what ya did but man you dont have to defend what ya did on every single thing. Anyways super neat vid.
@@HomeGaragechannel btw one time I did the silicone sealant on a sump thats where i think I'm not sure if its a fact i learned the gasket for the pump offers crankshaft, endplay clearance ,it wasn't major ,but it was noticeable enough to make me "squint an eye" and go hmmmmm! Wondering what that was all about!my question is to you would know if that's a true, to form fact, that a sump gasket can harm an engine if not installed ?
Honestly purchasing used parts was a stroke of genius! I was all ready for you to recycle the broken motor, and get a cheap harbor freight.

Some engines need the sump gasket for the clearance of the crankshaft

Good job! I would do the same thing with the sump. BUT, I usually don't bother rebuilding even with used parts. I'll get a good engine on a crusted out deck at some point - or convert a pressure washer engine with a deep blade adapter if needed. I would have no qualms selling this as a good, used mower if I were in your shoes.
thank you Matt Wickert. What you're doing is the smart choice, I'm just doing it for fun.
Yes, it's only a lawnmower so it doesn't matter but I bought a new crankcase gasket for it because it's the standard 0.15 millimetre thick gasket which maintains the correct amount of crankshaft end float.
I only spent $50 AUD on parts in late 2019 on my old 1988 model 3 horsepower L headed Briggs & Stratton lawnmower engine which included new piston rings as well,I reused the original 31 year old cylinder head gasket as well.
I did hone the cylinder out as well although they all say that you're not supposed to,it does blow a puff of smoke when first starting the engine but it doesn't use very much oil now & the spark plug runs grey now instead of black & oily like it used to.
I don't have a problem with how you did it because I probably would've done the same thing !
wow nice to know you reused the gasket too, and that it worked just fine.
Very interesting and educational. Its obvious you really know your stuff.
I would have bought/found a used motor and re-powered the deck with it but that wouldnt have made for as good of a video.
thank you Amc31b and I know just enough I would say. Your idea works well too!
Reminds me of the Snapper Sp80 I found 2 weeks ago same design and looks identical 👍🏽
nice, I hope it was in working condition?
@@HomeGaragechannel Yes sir I'm still trying to figure out why they dumped it🤔 Took it home changed oil sharpened blade through in a clean filter and she's been running every since✔️
It was a good idea to buy a used piston and rod. I would have done the same exact thing but I would have bought some new piston rings, that is the only difference. Keep up the good work. 😊👍🏿 #stihlpower #stihlisyourdaddy #stihlrunstheyard
you bring up a great point about the rings! thank you Patrick Poulard.
Instead of a string, I use the large reusable twist ties HD and Lowes carry for cables and hoses. Keep them on my equipment to hold the deadman to run the fuel out after the fuel valve isclosed.
that works too!
I found this video very interesting even though I would not have rebuilt the engine. I would just find a used complete engine. I have successfully resealed a sump but never tried the copper spray for the head gasket.
yes your idea would have made a lot more sense Brian King.
I don't tear into engines at all too time consuming . I have a couple of motors kicking around because the decks are usually the first to go so I would have but one of those on instead ! I would change the cam out though ?
thank you Bill Clement and yes the camshaft is here now, and I'm working to get it in now.
I've used the copper coat spray for years, works great on low performance engines. Nothing wrong with gasket maker - most of the time an engine like this will never again be worked on.
Great point!
Use for spare parts. I had a good chuckle about how you had fun with engine because somebody had to have a go and it makes great entertainment. Hopefully no one will try this on a decent engine ??? Go to Pakistan and see how they rebuild crashed vehicles.
you make a point
This was still a great learning experience for all of us, and I appreciate your reflections on the mistakes you made and how you could have done it differently.
No problem with used parts, as long as they are in good condition and it is within reason/safety.
I've had to use copper spray for exhaust gaskets (in good condition) on the connections between exhaust pipe flanges and had no issues.
As for the gasket maker/sealer, it has become commonplace for automotive manufacturers to use that instead of an oil pan gasket on newer vehicles. As long as it is compatible with engine oil, I don't foresee you having any problems using it.
Did you know that some newer Honda small engines use a timing belt?! Supposedly, they are designed to last the "lifetime of the engine" which I guess means when it breaks, everything else breaks? 🤷♂
I live too far out from any nearby towns, the roundtrip alone is easily an hour or an hour or more, so I always have to make the decision to make a separate trip for one or two items or wait for the next day and get it after work (if it is available in town). It is even worse on the weekend. This has led to some...creative...other ways to get certain things done.
I look forward to the performance results after it gets some working time in. Saved another one from going to an early gra... landfill! 🐺🔧
all honda OHC engines use oil bathed timing belts i've seem them last 2500hrs and i've seen one snap but due to all honda air cooled engines being non-interference engines valves do not open into area where the piston travels they just sputter to a holt new belt and back in business
thank you Jonathan Sherwood, I appreciate that. And yes the timing belt is bathed in oil. The interesting part, is that I've never had one of these, with a broken belt, even the neglected ones.
you are correct!
@@HomeGaragechannel Right?! Makes you wonder how long these belts really last? Without hour meters on any of those engines, going to be hard to say.
Wow your resourcefulness is very impressive. I would have trashed the whole project.
I probably should have taken a different route but lots of people seemed to enjoy these types of videos. thank you Sam Feldman
Good video! I find myself weighing out the cost compaired to what I might make selling the equipment. I have a Cub Cadet electric start walk behind mower with a rod knock. I am looking for a used mower with the same sized engine to swap. I will hang onto the mower as it looks like new. I will not be breaking any engine down like you did. The labor involved for any shop would be enough to convince anyone that it wouldn't be worth fixing that mower and it would end up in a scrap pile.
very true about the labor, that's why I do it myself and it's kind fun.
That's what happened to mine,I had it running so hot,I think I collapsed ring,boy was it fun rebuilding though,next to new!
nice work!
There is nothing wrong with reusing the old gaskets if it is still in good shape. I have reused a bunch of old gaskets and never had any issues.
thank you AJ Restorations
Where do you buy your parts or new engine?thanks for the knowledge
Thank you Gene1984 G I order from Amazon and Ebay,
on my lawn mower if I pull the "safety bar?" and then try to manually spin the blade it gives a bit of a groan and seems like it needs to be oiled, or in other words it seems like it has difficulty spinning freely. I was just wondering if this is normal? I have tried to put oil at the base of the blade's axle but it doesn't seem to have helped much. what would you recommend I do for this?
thanks for the question, what kind of mower is it? a model and serial number would help me to see what it is you're working on.
Could you gasket problem be solved with a gasket kit? I had one where Just the head gasket was $8 but a full kit was $13. And I needed the sump gasket anyway. The remaining unused gaskets are in the sleeve they were mailed in, in my garage filing cabinet.
hey you make a great point. Unfortunately, they aren't that cheap anymore
I have a Toro super recycler that i bought last year that, even after 2 months of ownership, oil started leaking out of the same valve cover gasket. The engine is practically the same as that one, but probably a little bit bigger. Theres a huge design flaw with those OHV gaskets or the cover as it has a habit of crushing the gasket when you tighten the screws rather than just tightly seal. And heaven forbid you open it when it is warm cause then you need to wait for the damn gasket to cool to shrink back.
I ended up replacing the original gasket with a new one and even after using the new one for 3-4 weeks, it too had started to leak oil from there again. I was seriously fed up as it was a new purchase. But eventually it seems like either the rubber melted to the right shape for a proper seal or the dust after me dethatching created a scab of sorts around the OHV crevasse as it hasn't leaked out oil since last year thankfully.
thank you for the information, and yes it would seem it's some sort of design issue. The strange part is that I've seen this gasket in either rubber form, or as a rigid thick paper gasket. If I had to replace it, I'd like to choose the rigid one, instead of the rubbery one.
@@HomeGaragechannel The one I have on mine is rubber. I've always found it so odd that it isn't more stiff. Is is very flexible and maliable and it does not enjoy being removed and put back. Also tears very easily too as I found when it stretches during operation internally, it seems like it rubs against the threads of the screws as my first one developed a tear after just reinstalling it a couple of times. I ended up purchasing a pack of 3 of them and luckily the new one ceased having issues. But if I ever have it happen again, I will just go with a stiff one.
I also feel like the oil runs up the threads of the screws as well when it thins out when hot as the threads on mine were always covered in oil as well. Always the bottom most one too.
Yep, used parts is the best budget friendly way to go!
you got the right
Remember the engine I was talking about that wouldn't turn? It would make 1/16 of a turn then make a thunk and stop. Turns out the rings gouged out the cylinder. I'm still going to try to run it with only one ring, but it's not gonna be pretty!
thank you for letting me know
I had one that quit like that. I just got a predator engine and put on mine 3 years later still running like a top, also one pull starts all the time
nice, unfortunately my harbor freight doesn't carry the mower engines anymore.
You can glue that gasket to the valve cover with that motoseal or what ever you used for the sump gasket.
yep, you've obviously seen into my mind already.
old timers would approve of the copper spray.
yes they would
I've considered using a torque wrench a few times, but it was only for a fleeting moment. I have never used one, and I have never had an issue.
for certain situations I would recommend it, but it's not required
I was sitting here nodding YES all through this video. I MIGHT have got a new piston and rod BUT maybe not and I use a LOT of 2nd hand Ebay stuff. I just have to try and be careful to get what I need and if I have a question I always contact the seller. Gaskets? I'd reuse the head gasket and lay the #2 to the sump. I've done that more than once too with no leaks. Torque wrenches? I have a walking beam and a micrometer that will go to 250# but with head bolts it's usually an 8 inch combo box and pull the bolts 3 or 4 times after oiling them up first. I pull a head a lot tighter than factory and anti-sieze the threads but have never had any trouble with any stripping, breaking or backing off. And as far as cranking, if the rope is running around the outside of the pulley, THERE is where the most pulling power is and easiest starting. Waiting on the next one and Happy Weekend!
nice! thanks for understanding my thinking.
Some of the comments have not be very "understanding" to say the least.
@@HomeGaragechannel Some of the commentors, probably the biggest part have NOT walked in YOUR shoes and mine are too big and stinky for most to mess with. It's easy to run ones mouth out of an armchair.
Hey just curious whats you favorite websites to get parts from?
craigslist and FB marketplace
Hey I got a Ranch King Rider and it runs kind of rough. Do you think it could be a valve lash issue?
if you don't know when the last time the valve lash was inspected, then yes there's a good chance
@@HomeGaragechannel thank you
no problem
I would of got new gaskets but what you did is fine.
thank you
Great video! I have a question for you, I have a stihl fs90r and it idles good but will not rev up and the head does not spin, what do you think it could be?
hmm. now they may be the same issue. Without the engine speed changing much the clutch may not be spinning fast enough to engage. So I'd work on the engine issue first. have you looked at the spark arrestor screen for a clog?
@@HomeGaragechannelI had bought it from someone for cheap because they couldnt fix it but it surprisingly didnt have a spark arrestor screen on it
@@HomeGaragechannel what else do you think I should look for since it doesnt have a spark arrestor installed?
I would remove the muffler and check the exhaust port, on the engine. The port could be blocked there. Then I would start and run it without the muffler and see if it still does it then. If it's still doing it, then the carb needs to be adjusted or serviced
@Home Garage Thanks for the help I'll work on it tomorrow and let you know how it goes
I think it was the right decision also. I didnt think it had that much compression from that rebuild
thanks
Most of the time, experiments, to prove a certain points, are fun and pay you back, despite the outcome, if cost was calculated aswel.
very well said
For home use , it's perfect , i wouldn't sell it without getting new parts though.
you are absolutely correct.
I had a box of parts off of scrap briggs flat heads. i was putting together a vertical shaft 4.5 hp block. i didn’t have rings. so i used a piston and rings out of a horizontal 5hp made in 73. swapped wrist pins out and they fit perfectly. permatexed all gaskets accept head gasket. valves out of idk what. rusted gas tank. threw on a mower deck and it’s been running no problem for 3 years. sure i have a better mower. but seeing it run for so long is crazy.
nice work!
@@HomeGaragechannel yea it always fun to scrap something together and see how far you can go with it. let it sit outside all winter with old gas. i just went out and 3 primes on the carb and it started 1st pull.😂
Great job
thanks
I have a craftsman lawn tractor with a v twin engine and the reading of compression is 145 psi, how good is it?
is that for both cylinders then? if so, that's pretty good
@@HomeGaragechannel 145 and 140
@@HomeGaragechannel how much use would that be?
nice
I'm not sure what you're getting at with the comment "how much use would that be?"
The problem is a lot of these newer Briggs & Strattons are putting things like “never change”. Of course average consumers fall for it and this happens.
yes you are correct
I save all the gas i drain from my small engine equipment and use it later as a cleaner/degreaser.
I save part for parts and start brush piles with the rest.
@@lewiemcneely9143 I use it to kill brush/cactus in fence line.
nice!
I will soon be rebuilding an 1978 Briggs 5hp engine, and if i can find used parts in good shape I will certainly use them.
good luck with it, and I think you'll have a great time doing it.
@@HomeGaragechannel Thanks!
Who do you like dealing with to by your new and use parts
I only use Amzn because of tracking and their return policy
I would have done everything you did apart from (1) a new head gasket (2) a used cam shaft with compression release (3) a new valve cover gasket. Everything else you did, I have no issues with.
Thank you Dee Bee, I plan on addressing these issues very soon.
I think you did a great job. It's hard to spend top dollar on something if its not going to be worth it. If I were keeping it for myself I would definitely follow your ideas on repairs. If I were to sell it I might hesitate. It would suck for it to fall apart after selling it if the repairs didn't hold. The main thing that kept coming up in my mind is how cheap engine manufacturers have become. So much plastic all the way down to the camshaft. Then they have the nerve to sell those mowers for top dollar.
you make a good point, and hopefully it works for awhile.
Use parts are a winner for sure
I use aluminum paint on old steel head gasket s
thank you Phillip Hall.
@@HomeGaragechannelI watched my Dad do it in his shop for years and he allway did it on lawnmower engines, I only seen him buy a few new gaskets in all those years
This was a good fix. I would've either taken the route you did, or more likely, waited for a free mower with a rusted deck to come up and just do an engine swap. But that wouldn't make for as interesting a video.
that works too, thank you Aylehouse
I'd do the same as you, except I use Hylomar on the head gasket.
I had to look that up , and yes, that looks like great stuff. I need to buy some more soon, I wonder If I can get that here?
@@HomeGaragechannel good question. I’m sure you should be able to get it there.
I was a backyard auto mechinic. My family would on a weekend - pull/disassemble/get parts ( 30 miles away ) /put back together in a weekend.. this is my thoughts - if you had such a catastrophic failure, buy a new or used engine. why - the possiblity of metal in the oil pathways. I do not know what is on a lawmower engine but they run through the whole engine of a car. If I was to keep instead of sale - I would cross my fingers. but to sell and risk a return - for me - no. - so tell me - are there real oil lines like a car engine - or something else that would not hide loose metal.
son this engine there is no pressurized oil passage. It's only splash oiling. There are oil return channels but they quite large.
what is with all the haters in the comments? good Lord it’s a lawnmower, not a small block 350! I think what you did was smart, breathe life into a old machine.
Don't confuse critics with haters. Its the same with a little bit of joking around and "trolling"
I know right.
man so confusing!
True
@@HomeGaragechannel where did you get an the used parts?
I have a 3D printer which I understand most wouldn’t. But I totally would have tried to print that valve cover gasket from tpu if I couldn’t get it to reseal.
Ah!!, that's what I need to get next!
i would have rolled it over to the spare parts corner
if I was a smart person, I would have, but I've got a few issues, so what's done is done.
One thing not shown is if you cleaned off the crank bearing of any aluminum from the old rod. That has to be smooth or your going to blow the new rod.
good point but not needed on this one, no aluminum was deposited onto the journal. Thank you Al's Repair and Restoration
The only real difference in what I would have done is to replace the camshaft in the first place. When a part like the compression release is broken, I have to remember that the engineers would not have spent the money to have it if it wasn’t needed. I’ve been down similar roads too many times.
yes I have sense changed it and you'll be hearing how I made a terrible mistake but the reason was spot on though.
Hey bro, what's up? I honestly don't mind spending my money to get my equipment running properly again. However I weigh the pros and cons in order to get my equipment running again. If my cons outweigh my pros well that's the route I'm going and vice versa.
you are correct, this one was a very close call for me, but for someone else it might have been different
@@HomeGaragechannel you're sure right bro. For someone else it would of probably been used for parts or recycled.
What why are gaskets so expensive??
Reusing the head gasket... these aren't Formula One engines. They work quite well with minimal care. When I raced go-karts, every week I would remove the head, and re-set the valve lash. I did NOT replace the head gasket every week. But I WOULD find a way to put the compression release back in. Used cam or new. The cheapest one you could find.
Repairing this engine, I would have gone cheap route like you did if I had access to the used parts.
good choice and well said
If you're going to sell a repaired unit, it pays to do it tge preferred way, since a come-back would cost you even more $. New gaskets are a good idea.
I completely agree with you
I liked your experiment regardless. Is this engine worth fixing? No, to me it isn't worth purchasing brand new on a piece of equipment. I would sooner go for a PowerMore engine over one of these, and in fact, I have, at least once on a Cub snow blower. I also had experience with one on an MTD made mower and it seemed to be a reliable little engine.
I can understand your feelings about it. The cost was my main restriction because the engines are not worth, all that much when used.
👍🏼👍🏼👍🏼👍🏼👍🏼
thank you !
well try option 1 first with new parts and if that,s beyond my penny prices i,d go with option 2 and see if that works out for me etc.
great advice.
i've been trying to sell a rider in good working condition for $300 , but had no calls . it seems insane that a pushmower can cost $500 . modern times .
I know right!
Adding it into a video for potential revenue from UA-cam should bump up the turnover 👍
you got that right!
I did not see you do anything to the crank journal this all kinds of scrapes and gouges on that that you should have taken off before putting the connecting rod back on it's going to transfer to the connecting rod and then freeze up.
So the crank journal was in pretty good shape, surprisingly. There was no aluminum on it from the rod and if there was I would have take it out to polish it, but it wasn't needed this time. So no freezing up here.
With a bag and fully working. I only gets 260 and if I take anybody trade in, it wouldn't be feasible for me to put a new motor on one of these
I know right, cost is just too high
I really like your channel and i agree with most of what ya did but man you dont have to defend what ya did on every single thing. Anyways super neat vid.
thanks and I wouldn't call it defending my choice, but I do like giving my reasons, which I don't think I do a good job expressing.
Go get a compression release and valve cover.
that's the plan.
Weird question are you a megadeath fan im just curious
Used engine on the way ohhh yeahhhh!
actually I have a different idea.
@@HomeGaragechannel ohhh yeah,well!! can't wait to see the thought process, bet its gonna be cool!
@@HomeGaragechannel btw one time I did the silicone sealant on a sump thats where i think I'm not sure if its a fact i learned the gasket for the pump offers crankshaft, endplay clearance ,it wasn't major ,but it was noticeable enough to make me "squint an eye" and go hmmmmm! Wondering what that was all about!my question is to you would know if that's a true, to form fact, that a sump gasket can harm an engine if not installed ?
to be honest I'm not sure, but the clearance was the importation, I wound't rely on using a paper gasket.
There’s a time to just stack it back for later
there sure is
