- Be aware your machine will more than likely be on borrowed time and start to burn oil after this. But it will still be usable if it works. Make sure to check your oil regularly after you unstuck an engine.

I USED this on my lawn mower, Craftsman 6.5 Briggs and Stratton that I have had since June 2005. After replacing the starter rope the it was still frozen/locked. I was within. 2 minutes and 4 F-BOMBS left of spending $350 to $400 on a new mower……when I used your solution! Like you I said “what the hell let’s give it a shot”. Put the proper amount of oil in (…which frankly over the 17 years of use I NEVER did….) and “unfroze” the blade like you showed, and it ran like new!! Thank you, thank you, thank you. It’s solid AMERICANS like you that take the time to film a possible solutions to help us retired broke dick 66 year old Marine fix it himself. 👏👏🍺🍺🍺🍺🍺🍺!
😂
“Tight! Not in a good way” lol.
Great video
My brother found a 1958 or 59 craftsman rototiller that had not been used since the mid 60's in our grandfolks barn that was seized up and he poured Marvel Mystery Oil in the sparkplug hole and let it sit overnight and it worked! He put fresh gas in and changed the oil and it runs to this day (May, 2020)!
Do you still have it
Marvel mystery oil in absolutely a super awesome product LOVE IT !!
And he found it / unseiezed it April 2020😂
I've unseized two engines successfully so far; one was a 1970s Tecumseh 7 horse mounted on an Ariens snowblower chassis. The original owner ran it out of oil and gave it to my dad; I was able to unseize it with WD40 and a pipe wrench (my plan was to replace the engine anyway), but sure enough; it ran for an entire season of snowblowing before I revved it to the moon and snapped a valve stem collar. The second time was actually my Honda motor scooter; I was barreling down the highway at around 75mph (it's a freeway-legal 250cc model), and the oil plug fell out (I recently changed the oil and got distracted before I torqued it down... whoops!) and the engine locked up. After letting it cool and filling the crankcase, she's been running fine (compression is perfect) ever since. Eventually, the engine will need a rebuild anyway, but I dodged a bullet there.
Hey man ya this is the only one I have personally done before. It's a total crapshoot sometimes as to if it will work and even how long it will last. I remember that video you put up of when it happened to your scooter you def got lucky there man, how much does a rebuild kit run or even a good used motor for one of those go for? Are they easy to find?
+hanksranger A proper top-end rebuild will cost me north of $700 using all OEM parts. A Chinese top-end will cost around $250 complete. Since I place zero faith in Chinese knockoff parts, I'll be spending around $700. A complete used motor will cost about the same, but without knowing the engine's history, I'd prefer to just rebuild it myself when the time comes.
+BBISHOPPCM's World interesting, yea I can see that. My boss was actually given 4 chinese quads with copies of the 125 motor that honda makes, all the honda parts do swap over but I honestly wonder how long those copycat motors last compared to the real thing. Makes sense to just rebuild though over going used hell maybe you can have it bored and stroked for a little more power perhaps?
These Tecumsehs are good engines and pretty tough. They do like clean and full oil though. LOL. I picked one up like this from a neighbor two doors down, he replaced it with a $500 Toro from HD. I initially took it for parts and then got to freeing it up the same way you did using heavy gloves and rotating the blade. Added oil, it still had fuel in it, unjammed the starter cord, tightened a loose wheel and in 10 minutes I was cutting my lawn with it (that was 1998). I still have the machine, although it's in my "retired" pile since I have newer ones to use. I used it for a full ten years every week. The machine was already ten years old (made in March 1988) when I got it. AYP made Sears Craftsman (like this one) with a 3.5 hp Tecumseh. My neighbor was shocked to see me using it. Fast forward to 2019 (that neighbor moved away). Guy next door to him throws out a 2007 MTD push mower. I grab it, and same thing, unjam the blade. The real problem was it being over filled with oil. For $1.78 for a new plug, and air filter (which I had already) and correcting the oil level, I got myself a runner. Fires right up and works like new. Again, shocked neighbor.
This weekend's find was a Devilbiss pressure washer with a Briggs engine. We'll see what happens here.
That’s awesome man
That Tecumseh engine in this video, are the best. My dad had that same mower when I was a kid. We had it for 20 years, and it never gave any trouble. Always started first pull year after year.
we have a newer one that met it's demise this weel
Thanks.. worked like a charm . Mine had seized after sitting out back under a tarp for about three years. I never once tried to start it and today I decided to give it a whirl and it was locked solid. I couldn’t even move it with my hands. I still had oil in it so I added a little more and sprayed some wd40 in the cylinder and she freed right up. After about five pulls on the cord she fired up so thanks a lot.
I have sold some mower's for cash. I always have a soft spot for Tecumseh's . They get a bad rap but I like them and always fix them first. never had any issues on returns , never. cool work instead of just trashin it. ripped apart a newer Briggs the other day. had bad valve guide and low compression . I was amazed that they now use a plastic cam shaft. :[
roo
People give Tecumseh too little credit
Those older Tecumseh’s were actually respectable
I like it when I have so many of my own mowers to choose from to mow with and sale . I've done made a decision that I will not even offer any money for a Tecumseh mower anymore. Parts are too hard to get unless you buy them new . And one can loose buying new parts if you aren't careful . Enjoy your videos - thanks
Yup. I generally don’t bother with them anymore. If the deck and bag are both in good shape I’ll pick it up to swap a briggs on too it instead.
I've unsiezed a couple of old mowers, one was a Tecumseh, & it ran for a whole season then crapped out, just freed up a Briggs the other day & it runs great, I'm keeping it for a beater mower. some of those older mowers can surprise you, they really made them to last back then.
Ya very true unlike a lot of what is around today. These new motors are made by bean counters not engineers
+hanksranger not hondas lol
I like how Craftsman is written on the deck in those massive red letters.
I love when people throw mowers out on the garbage!
Very good video. But I have to say, the reason why the engine ceased was that your heat-dissipating fins on top of the cylinder were extremely clogged, causing more heat. This breaks down the oil, causing it to burn then cease. Always clean your fins after every 5 uses. Dirt and oil build-up are the lawnmowers' enemy. Degreaser or even auto brake cleaner spray does the trick.
Of course, check your engine oil periodically. Change the oil after 15 uses. Check, clean, and gap your spark plugs to specs. Clean or replace your air filter. Check your blade for any cracks or dullness. Replace if necessary.
And lastly, always use a Portable fuel filter by Mr. Funnel. (Mr. Funnel AF1CB Fuel Filter). When storing your lawnmower, remove all gas from the tank, then run your engine until it shuts off on its own.
This will make your lawnmower last for a very long time. Keep these videos coming, I really enjoy them. :)
This machine was a trash find
@@hanksgarage_ Nice, I was just giving out tips. Keep them videos coming. :)
"She is tight though, and not in a good way" lol
Thanks bro for your help ,my lown mower is back on the yard working,
Thank you! Thought I blew up my engine. This worked first time!!
This is hopeful😅
"OMG" !!!!
WHAT A GOOD CLASSIC RELIC
.
Wow, hard to believe you can get some of these old motors to run, I have trouble keeping good looking used mowers running.
Not bad for a old Tecumseh. I had a old 3.5hp briggs that was seized so I put WD40 in the spark plug hole and let it soak and manually turned the blade and got it free but it had a thing where it would act like it was going to start but then would backfire well in one of these cases it had leaked gas out the exhaust and when it backfired it caught the mower on fire! later i was stealing the blade brake cable and it managed to leak gas all over the garage floor just wanted to be left alone lol. But I helped a lady with her mower the other day she when I went over she was like arent you the lawnmower master? im like yeah I guess lol my neighbors have seen me take in and fix many mowers since I have lived here but she couldnt get it started it was a Honda and niether her or my dad could figure it out until I pointed out the fuel shut off valve was closed I had another lady a year ago who couldnt get her Briggs started and I pointed out the spark plug wire was unplugged and thats why it wouldnt start and she gave me $5 for helping her lol the people you run into
+Theghostmaster 87 thats for sure man, I love easy fixes, and ya some people just literally have no idea about anything
+hanksranger Im just surprised this Tecumseh didnt have carb issues for how old it is thats how I deal with them if I find them see if its a easy fix or not my first lawnmower was a Tecumseh and I went through the carb a few times and it only ran off starting fluid for a few seconds plus the gas was getting on the deck and eating the paint so after seeing they wanted $60 for a carb I gave up on it
+Theghostmaster 87 ya unfortunately I've had to do the same with them. I get a lot of people asking me why I don't deal with more Tecumsehs but I always try to tell them it's because parts are not cheap. They are usually Atleast twice the price of Briggs stuff if not 3x more. I do give them one chance though before I give up on them
+hanksranger Yup I agree with that they arent worth the money I give the carb a quick cleaning and see where it goes, not worth the time if it takes more I mean even the carb rebuild kit for my Briggs quantum motor was $30 and the diaphram gasket for my Briggs classic carb was cheap plus a bit of carb cleaner and both were good
Worked like a charm.
just had one to seize this morning i'll try your remedy, Thnx for posting it
If you want to get rid of some of your mower hoard you could remove the engine from the mower body and make a frame for the mower engine and a car alternator and sell them as a generator once you fit other necessary things to make it work as a generator.
I have two BVS153 mowers... they're perfect, awesome condition, one problem, they both burn oil.... I'm mowing with them everyday, they never let me down
She is tight though and not in a good way! Lol
I bought one of these back in the 80's? Never had a problem that a simple tune-up could not cure. Never ran it low on oil though. Your supposed to check the oil before you start it. I guess some folks dont know that perhaps... Still got it and it cuts my property line once a week.
Yea it’s not the only seized machine I’ve found in the trash
i enjoyed the video. if you having trouble finding use for it, you could always sell it for less and offer to take it back if it dose not get them threw the summer... or just give it to some one who needs it, i was in that boat once.
RockeyDAproductions yea good idea but this one has long been sold they never called me so I’m assuming all was good. Thx for the sub subbed ya back
well thanks right back at yah then.
Thanks It worked for me.I had to use hammer to turn it.but now it’s working good
fixing it right up like Ricky would when he ran for assistant trailer park supervisor!
Lol! Right? Like when he found the car exhaust and stuck it in the trash bag. That shit was hysterical
+hanksranger a real find! as long as you don't open up trashland i don't think anyone will mind
+jsplicer9 haha ya garbage land and bubbles got all pissed that was one of my favorite episodes.
It's 2020 now, what ever became of that mower? How long did it last? One thing you could have done with it is give to some young adults renting their first house. I remember the first house I rented back in '78 and the landlord expected us to keep up the yard but didn't have a mower to give us. I would have gladly have paid 10 or 20 bucks for something like this! Anyway, good video.
A challenge is always fun. especially when it works out. man that things purring! I actually free'd up a rotary motor using seafoam and oils before and the motor ran for years. it could still be going. i just lost touch with the last owner.
+paradoxdesigns Yea hopefully she stays solid I like these older motors man,.
Those old Tecumseh Motors are pretty good
I'am Your Newest Subscriber Great Videos
Is this still running a couple years later by any chance?
Aw ha . Maybe their is hope for my dilemma . I'm going to try this in the morning . Thank you :)
I wouldn't own a Tecumseh. I worked for them for years on the carburetor lines in Salem, IN and they're junk. Take a briggs over them any day. Their hydrostatic transmissions are great (worked on that line as well) We used to try our darndest to tear those things up and they'd just keep right on working, but the carbs were crap, lol.
I have one just like it we got brand new, my wife used it at the lake and seized the engine and brought it back home. I got it running again and been using it ever since, two pulls when cold. Only thing is we've run the thing so much the wheels are wobbly because of the axle s becoming worn
It will seize up again, ive never had any luck with seized engines (trash picked mowers) staying unseized, damage already done. I had one mower that i unseized, and a month later blew a hole through side of the block (kinda scared the shit out of me). It was nice vintage snapper with cast aluminum deck, i ended up finding a nos engine to swap with.
I have noticed any number of trashed mowers at the dump - wonder if it is because of ethanol clogging up the carbs ?
I also noticed this engine runs at the correct factory RPM of 2850.
me too
Had the exact mower and gave it to a relative....it was a great mower
Right on
For future professional home owners an unseeized engine benefits from running on 2stroke fuel even if it's a 4stroke for the rest of its life.
incredible
Those old motors are so much tougher than the modern motors. Keep oil in it and I say she runs for years. Anything is possible but I have unseized a few engines and used them for years with no adverse effects. If I wanted to sell it, I would just be honest about it and say the motor was seized when I got it but it came around. For $40-50, people will see it runs good and just buy it. Its old, its used. You could sell them a 3 year old mower that hasn’t been seized and it could still blow up next week! Most engines blow up because they are abused and/or neglected ... not because of poor engineering.
The newest Briggs in fact are poorly engineered. I’ve done a few videos on them. Busted oil sumps, starter cups, recoils etc. They are made to a price point. Gone are the days of the 3.5 horse flat heads that run forever.
I love my old Tecumseh.
Thank you for the good ideas.
That things is a beast, definitely would be a keeper if it were mine. Is that Rotella for diesels only like it says on the front? I wanted to try it out for my mowers but it all said for heavy duty diesels on it. I've been using Castrol GTX and it's been a damn good oil. Do you ever come across newer Hondas?
+ChicagoSirens Its fine just massively over kill for a lawn mower, the guys on bobistheoilguy forums have run it in mowers before with no bad results, it just exceeds manufacture recommendations. Ive not had any issues with it yet. No on the newer hondas, in fact I hardly come across them most common are murray, mtd, bolens etc with either briggs or tecumsehs.
+hanksranger I might try it. I want the best for my 2015 Honda. Those Murrays MTD type mowers are very common around here as well, but I have seen more people going with new Hondas and Toros recently!
+ChicagoSirens they might want you to put 10w30 in it. Castrol makes a good oil though. I've used it in all the cars I've had for years.
Thanks for this video. It answers the very problem I am having. Can you tell me the model of the engine in this video? I have an old craftsman with this Tecumseh and need to order a couple of parts. I have searched all over the engine and cannot find it. Not having the model number makes it a guessing game. Thanks for any help you can give me.
Is that a ham radio antenna? Thanks for the video!
Cylinder head fins could also use a good cleaning
Hey Hanksranger that's great and old Tecumseh can be saved!
Hopefully it stays like that
+hanksranger
Like I said in your latest new video, the engine on my 1984 Toro had a new carburetor installed in 2013. However, some of the BBC-related parts underneath the deck are going bad due to age, as the engine is struggling to draw all its speed to the BBC assembly when engaged (factory engine RPM is 3000).

Did you squart that oil into the place where the sparkplug belonged. If so I need to try it.
That’s exactly what I did
I just got a hondo mower walk behind the lady said it’s dead do y want it. I said yes. Went to pull the cord and it’s extremely hard and recoil is slow.
What’s your suggestions.
Thanks.
Sounds like the engine might by tight. Do what I did in this video and see if that helps. You’ll have to take the recoil off and take the center bolt out, use a little wd40 inside of the hole and put back together. Don’t do anything more than take that bolt out. You’ll risk unwinding the spring
THANK YOU!!!
I'd like to see you try to unseize your earlier '80s Tecumseh. I hope you can save up enough money to fix that one (the red engine).
+hanksranger
I hope you find those rings sometime. Order part nos. 35544, 35545 and 35546 if that engine is an ECV100 (4 HP / 10.0 cubic inches), or 28986, 28987 and 28988 if the Craftsman engine model number crosses over to a TVS90 (3.5 HP / 9.0 cubic inches) model. This black one indeed crosses over to a TVS90.
Just did a quick search based on model of mower and motor that is supposed to be on it. Need to check model on motor when I have time but like I thought rings aren't available new sadly... However I can take a gamble with used parts which are available
hanksranger
eBay is also a useful site to search for NOS (new old stock) parts for your engines.
+ClassicTVMan1981X here is the part number for the red one 131.907742 I found some complete piston and rings on eBay but nothing new yet. Not on computer right now either looking on my phone. I'll search some more when I get back to the house
hanksranger
That engine is a model 143.324022, which crosses over to ECV100-145194E.
I have a Yamaha similar design in mint condition. Ever seen one? It’s on my channel
You know what they say about old machinery
Sell this on ? I've scrapped loads as they're not worth anything except their weight.
Have you ran in to a Lowes branded MTD mower from the 90's? I have one in my shop right now, and just replaced the carburetor and fuel line and it still wont start, not even an attempt to start. I checked for spark, and it does have spark. I dont think its the flywheel key. Can you point me in the right direction? Thanks!
hows the compression feel? Make sure the primer is working and no air leaks anywhere around the carb, also try spraying start fluid into the throat just to see if it will kick over
Do you still have that old lawnmower! Or did you sell it
Was that a HAM antenna
Looks like he needs grass seeds also.
is it a thing over there with that engine brake lever P.I.T.A thing ? here if a customer askes we just remove it and move kill switch . is it a law ?
and those cheapo shower curtain plastic hooks are a good thing for holding them too . come with the curtain , and i always run out lol .
Yea somewhere in the 1980s it became a law lol
Hurrah!
How can u free a ride on mower engine
Lucas or duralub... And oil of course.
What is that lever on top of the carb for ?
its a manual throttle control
I am BIKE LESS!! My Honda trx 90 engine seized! First started making rubbing and scrapping noises, The first time it did it it cut off then a day later ran fine! About 5 weeks ago it was running but before i heard a slight clicking noise when i put my ear down to the engine so its rubbing and started running rougher i gave it little revs then it just shut off Now the back wheels are locking up =(
+Trucker boy 98 Man that sucks hopefully you can find another motor for it you can try unseizing it though like I did with this mower.
+hanksranger if we pick up the back wheels put in the last gear jerk the back wheels it won't turn but when we pulled it by a truck it was hard but I heard the pistons moving with the lubrecent it was tight!
Trucker boy 98 Yea keep doing that you may be able to unseize it, chances are it will seize up again and burn some oil but you should be able to get some more use out of it
+hanksranger It did get the shit used out of it! Acutely I just got chain fixed then it damn thing seized :'( We might just get a honda 50 were not sure if we are...
what did you spray?
I have couple of keepers, too. The scrappers a meth heads snag anything metal. Just plain luck to find one in PSL, Fl. Lately, though, I had a run of pressure washers, all with bad pumps, and motors that need minimal work, to carb work. Pumps are too expensive to buy and make any money on resale. Except for one I'm keeping for my use. But, the motors all run now, on the rest.
Nice video.
the scrappers and flea market fuckers around here drive me nuts man agree on the pumps too, ridiculous how they get you like that
What causes the pumps to go bad is that you need to run the water first, then turn on your open sprayer, then start the pressure washer. When turning off the pressure washer, make sure your sprayer is still going then turn off the pressure washer. Do not turn off the water until you have turned the pressure washer off first.
did it last a year?
Ooh and unseizing video, always wondered if it was possible...
+Sean “S3EN” Slater Oh ya its def possible, just a crapshoot as to if the motor will hold overtime
Wd-40 is ok for spark plug hole?
Yes it is
Do you have a carb clean video for this particular mower?
Not too old school, it has a primer bulb.
Tecumseh mower engines had automatic choke carburetors through 1977. There were also a few Craftsman engines that had top-mounted primers; those engines were produced from 1978-84.
Its a Craftsman keep it
wow!
Where's a good place to buy Craftsman lawnmower parts?
I use ereplacement parts, eBay or Amazon
do you still have it or sold?
+Forgott3n Gaming long sold why what's up
was just wondering if you planned on selling it or not you said in the video you werent lol
Forgott3n Gaming I ended up getting like 3 more of these
I think my dad has one of those
I had one
How big is your mower hoard?
its fluctuated over the years currently about 20 complete decks with motors, have maybe 10 or so complete motors on the shelf, and a few plastic crates for of parts, you can see it in better detail in my fixing mowers for money video I did, though it has changed since then
Can I use WD-40? Never will I ever loan out my belongings again.
Ill buy it for $20
Oo oo
“She is tight not in a good way
It decided to seize up? lol
Trashfind bud
🎉9
I'd throw it in the garbage tecumseh Slurps
can i have it for free
+Ed Bart You do realize how much it would cost to ship it to you right? I would be shipping it clear across the country.
Yep
can you show us your coletion
When someone actually likes shell motor oil 🤮
What’s wrong with it? Oil analysis say it’s fine. Or is it just you’re brand whoring another brand?
Tranny fluid can work wonders too for engines that sat too long
