So after watching I did get a few good take aways: 1- 50PSI is not too low for the machine to start. 2- Using a tap holder to lap the valves is so simple that its genius! 3-The guy that commented that this "big" blower is putting tons of carbon in the atmosphere is watching the wrong channel. 4- Junior is a good drummer 🎉 5-And lastly, Taryl should watch videos from a guy on UA-cam called "Taryl Fixes All". More than once have I have heard and seen Taryl say we need 3 things to make an engine run. Fuel, Spark, and Com-presh-yee-own. He also says the timing of the spark is important. Its always a good day when you learn something. Thanks Taryl. 👍 Zombie Dave
@@mikepink1337 Thanks Mike. I knew that before watching. Taryl stated in the beginning of the video that the 50 PSI should have been 100 PSI. And because I'm a little slow on the uptake I am guilty of dumping gas down the cylinder and just trying to get it to cough or run for a second or two. I confirm spark,fuel,and compression at one fell swoop. So in the video Taryl chased the low compression to the point of a valve job when it may or may not have been needed. So my comment was a round about way of saying that's 1 hell of a compression release.. lol Have a good day Mike 👍

I remember when nearly all landscapers used Stihl. They started becoming unreliable and now I see them using Echo. Taryl did a good job fixing this blower.
With the economy nowadays, people don't want to spend twice as much. They're both good quality, but who wants to be wasteful on stihl for the name. Not me.
I got a br800 and echo 9010, the br800 is way more agile/maneuvarble in tight spaces like behind shrubs, etc and is more quite. The 9010 definitely punched through the big piles better though, but loud as anything
Every piece of Stihl equipment I owned was hard to start when cold. I switched to Echo, starts right up every time, no hassle. Plus I don't have to get ripped off from a Stihl dealer buying overpriced parts.
@@petetrembath2537 yeah those motors are pretty good it’s all this New Amazonia world or this thing where all reading this and everything else now World has really been a mess. Everything, everything has stupid quality control SLACKERS! Buncha SLACKERS!
I am a certified Stihl Tech, best way to lap the exhaust valve is to use a small piece of gas hose and after putting lapping compound on the exhaust valve use the piece of gas line and put on the top of the valve that sticks out of the top of the engine then use a nail with the top grounded off and put in in a cordless drill and stick the other end of the gas hose on the end of the nail in your drill and gently pull on it to lap the valve. Works real good, then use brake clean to spray off the residue compound.
Wow your patience is amazing!!! You are a mechanical genius. They way you diagnose equipment is absolutely amazing. The mechanics when he took it back couldn't figure it out and you did, awesome just awesome!!!! Great video Mr Dayctal
its likely the techs (if certified) knew exactly the causes and flagged it. back packs are now to much work for the money. and telling the cust their better off writing the unit off. either way the cust is going to be pissed off and take their money else ware.
Wow, my Stilch blower has been GOLDEN!!!! No problems at all, except, well I had to do a valve job. Then had to put in new rings. Later on the spark plug blew out the threads so I put in a helicoil and fixed that. Oh, and the crankshaft ball bearings went out. But really nothing else. Except the carburtraitor snapped off, had to replace that. But that's about it. Oh, then the flywheel key twisted off like the one you are working on here. Had to replace the flywheel. That's it. It's been GOLDEN. Oh, I forgot the throttle cable broke and had to put in a new one. But that's all. Except one day the gas tank cracked and leaked all over, and had to replace the tank, but that's it. It's three years old, that ain't bad for a machine that's three years old. Yep, it's GOLDEN !!!!!!
This is all good to know if I find a new looking BR 800 on sale for less than $100. Lap valves, replace spark plug threads, remove flywheel, pin in key way and make witness mark on crank, red locktite flywheel. Keep an eye on gasoline tank, maybe bound reinforcement to some areas. Run a lower mix oil ratio than Stihl recommends. I use Stihl mix oil at 2/3 gallon rather than a gallon with REC 90 gasoline and a double dose of Seafome. I have to drive about 20 miles to a REC 90 station. Its worth it. Instead of a 50:1 ratio that gives 33.3:1 mix oil ratio. I don't get any smoke and I'm using it in a 1968 Sears Allen Bradly chainsaw. The Seafome makes the chainsaw sound deeper. Seafood is not a gasoline preservative. It removes carbon, encourages cleaning and is recommended for 2-cycle engines. With REC 90 I'm on my second summer old fuel and the mower starts on the first try. It is likely ethanol fuel in an engine dependent on mix oil for its lubrication that is killing the engine bearings. Usually a 2-cycle kills its cylinder piston contact surface before real damage to the main bearings. REC 90 is made for 2-cycle marine engines being stored through the winter. It has no ethanol and is intended for long term storage so it might have some other attributes. Shilh throttle cable and kill switch are weak design areas in older Stihl string trimmers. The leaf blowers seem to follow the string trimmers more than the chainsaws. The kill switch isn't really needed because it almost as easy to just choke out the engine to kill it. If buying new, Echo makes the most powerful string brush trimmer and it's light weight high reving 2-cycle. Echo's throttle cable and mechanisms are smooth and robust. Echo has a reputation for overheating in hot humid weather that I have experienced and will not start until a 20 minute wait in a cool spot. Stihl is harder to start, but are strongly heat tolerant. This is for older stuff in the 1990s. My Stihl FS66 string trimmer would get slow after getting hot. I think that is because the seals are not up to the task. Other trimmers use larger diameter seals. They seem to need to be Stihl made seals because even though a standard seal, non Stihl seals seem to leak and Stihl doesn't make their own seals for it anymore with NOS going for over $100 a set! The standard seals of this size go for $10. I'm going to try another brand of seals.
Chickanic down in Arkansas has been comparing the Stihl BR's to the Echo PB's on her UA-cam channel for a year or so, and she's come to the same conclusion as Taryl about the BR's. I've got an older Husqy backpack that gets homeowner use, and gotta say that I'm really happy with it. Clogged the rings once using bad oil, re-ringed her, and she still runs like a champ.
Echo makes some fine equipment...I've used it for many years. Still have one of the old metal-cased chainsaws that nobody ever gets rid of, just keep repairing them.
Good job Taryl. The dealer that looked at it, didn't want to see what was really wrong with it since it needed actual mechanical repair. There's your dinner!
I’m with you, Echo 2 stroke over Stihl 4 mix. I have the identical blower with a no start condition that just came in yesterday. Gonna check that flywheel key first. Thanks Taryl!
Nice clean bench Taryl. Don’t you love how it takes all day to clean it off and just an hour or two to get full again? Love the show. Enjoying the skits channel too.
Taryl, back in the day of Kart racing, I never ran a key. Simply put a tiny film of valve grinding compound on the inside taper of the flywheel, put it in time and torque to spec.. Never had one slip, turned as much as 7500 rpm on a Briggs and Scrap'em 5 HP.
When I was a landscaper we used all Stihl equipment and seen a decline in the way they held up compared to before. And this was awhile back. Most landscapers were switching to Echo equipment back then.
I have a Stihl ms170 with the cast-in flywheel key. It sheared off after about two years and 40 hours use. Most frustrating fix I ever had. Like the blower it would crank or not, maybe run great for 5 minutes then quit and not crank back. 30 pulls later may crank/run like new for a few more minutes. Had fuel and fire and not even hit on starting fluid. Stuck it under the work bench and just bought and used another saw till I had patience to not throw it away and tear it apart. Finally found the sheared cast in flywheel key that had the timing all off. Bought a $9 flywheel off ebay and it has ran fine for the past four years. That cast in key was a bad idea in my opinion, a designed failure point.
Years ago my buddy bought a Stihl chainsaw. We went to the Adirondacks to his camp to cut some small trees . I brought my 2 year old Jonsered saw. By the time he got his Stihl started(and was down to his t-shirt(Winter)), I had all the trees down. My saw starts on the 2nd pull every time. It is still running like a top after 35 years of usage !!
If you can't see where the valve is seated use a dab of Prussian blue on the valve and move it around on the seat and it'll leave a good impression. That's a great repair hack so thanks to Faryl for the info. Please don't shut that door so we can hear that lovely sound of the leave blower. I love that sound at 06:00 when the neighbor goes out there and "gets it on"-NOT!
I like to do a leakdown test before I tare engines down. Because if you miss 1 simple thing before the tare down the you run into a fog when nothing seems wrong internally.
Hey Taryl this is an awesome breakdown tutorial. I moved away from a lot of 2 cycle handheld repairs and limit what I do. The flywheel on these units should be redesigned. Excellent video
Its obvioua that they are designing them to fail, with all the materials science they cant produce a reliable product? Ive noticed the brands bosch, stihl and bmw ,merch have flashy products that just do not last. It all started with the mobius cartel in the 20s and 30s where light globes were made to fail.such a waste of resources and energy,there is nothing wrong with making business, but engineered obsolescence is undemocratic .
I have a brush cutter that was hard to start when hot, I thought it was the carb but it was the gap between the coil pick ups and the magnets was too great. When it was hot the gap widened and spark was weak. Did the business card fix and wala it works great. love the show! thanks!
When I was looking at a new trimmer I seen those 4-mix things. Decided piss on that, if I'm going to have to worry about valves and still mix fuel they could keep it.
I own a 25 year old Husqvarna back pack blower. It always was a cold one starting in the Winter. Always starts fine in the warmer weather. It is still running and all I have ever done is change plug, fuel filter, fuel lines, and some wiring repairs. Good piece of equipment.
Junior and I have that one thing in common, drums are a big part of my life I started when I was 16 and kept it up ever since I'm 26 now, it's a great hobby,❤
I learned something new today the 4mix are all p.o.f I will stick with my old BR400 because it was made when Stihl and Echo were equal in quality. Good video Taryl.
Thank you for showing all of the neat techniques you found in repairing this machine. A lot of the newer equipment is junk when I purchase it. I have a Craftsman edger that is almost thirty years old. It runs good. I have to lap and adjust the valves once.
Bought a new McLane edger July of 1980. Briggs engine, still runs like new, 44 years old. Still has the original spark plug. Just use straight 30W oil, change every year, keep the air filter clean, and they'll run forever. Have replaced the blade probably 15 or 20 times, but that's it.
That was a very good investigation video, you wouldn’t think 4 cycle would have the pressure issue of the 2 cycle, like the old saying says you learn something new everyday! Thanks for going over this piece of equipment great video👍
I own an Echo PB 9010. A beast of a blower! My one complaint is the wimpy detent on the cruise control. You slide the lever from full throttle to idle and you overshoot idle turning the engine off. Take the unit off your back and restart. Pain in the arse! I found that holding the throttle while moving the lever back helps avoid the overshoot, but, I now avoid the cruise control.
I was going to upgrade my gas blower this year, but then in Portland Oregon they just banned Gas Blowers. Weird, I still see even the city still use them. But ban them for residential users.
Go to work at the city, then have them help you get one. If you're good enough, they'll probably help you out. I did that once here, lol. If it has the city's metal tag, they can't keep you from owning it if you got it legally. 😮
I bought a parts br800 that ended up having a loose flywheel with a sheared key, I just cut a slot in the flywheel with a thin metal cutting saw blade and created a key from metal stock, and off it goes!!
I bought one of those and I was so pissed off at it because it was the same type of thing I had going on it would not start and I finally went back to a smaller blower because of this problem. Honestly the small one works just fine for me.
I have two of these blowers, one for over ten years with at least weekly use. The other is identical to the one in this video. NEVER a problem. I love them. I use non-ethanol gasoline in all my lawn equipment and synthetic 2 stroke oil.
Taryl - I was surprised when you said the piston pin bushing is not replaceable and you need to buy a new crank if you were going to fix it. In Australia for many years the Victa Mower 2 stroke 125cc and early 160cc mower engines had a brass bushing for the gudgeon pin. We would use a home made draw bolt using an undersize socket or pipe to pull the bush out. or set up a vise and press with pipes and or sockets. They was a replacement part but also there was brass or bronze bushings of different sizes that you could buy from engineering shops. Once you cut the length needed, fit it in the small end, by squashing it in with the vise, we then used a reamer and cut in until the piston pin ran smoothly through without any binding. It wasn't a big deal back then and the bushing lasted for many years. That exercise may take roughly 30mins to do. The reaming was done slowly which took a bit time. The point is, its repairable , if you could be bothered to pull it all down. The labour time makes it all beyond economical repair and no dealer I know would do it these days with their charge out rates. Like you point out why not use a needle roller in the gudgeon in the first place. Thanks Stihl.
I have 2 of the exact same blowers...Possibly the strongest blower on the market today. Our blowers start fine on usually the third pull. We use Stihl HP Ultra premix and run the machines hard..these things don't want to be at half throttle. JMHO
I know you know this but! 1st thing is check Stihl for a service bulletin for this problem. If none then check to see if it really is hard to start by putting some fuel into cylinder bore and then pull it over. If it starts right up you have a fuel delivery issue and you know the spark is good. If not it is the timing, valves or piston rings. Broken flywheel keys are common. Check that first. Glad you solved it.
Great job on that repair can’t believe the dealer it went to could not figure it out and that sounds odd they probably just didn’t want to work on it…👍👍
Hey Taryl! Thank you for sharing this video! I have been thinking about getting one of those Stilch backpack blowers for a few years now. Really glad I put it off. Mulching leaves is much better in my opinion. You don't have a clean up a huge pile after using a blower. Thanks again Taryl! Keep the videos and skits coming!!
I still have a stihl feeler guage for adjusting the valve clearance. seems like the clearance is or was .002. not .010. I remember the clearance was fairly critical
It has an easy start, when on back you pull cord halfway lightly than let it go back than pull forward lightly but quickly and it will start, I also learned that you can remove the side start and install the normal pull robe on back if you want
Honestly would love to sit down and chat with Taryl and his friends. They seem to have a real chemistry which reminds me back in the day when friends use to love sitting around and cutting up for laughs. They remind me of an old show I used to watch called the Big Chuck Little John show that hosted movies on the weekend. I am greatful for Taryls knowledge he has shared and his good natured comedic life. It saddens me that the gov is shoving this green deal crap and what angers me is a friend I have known for years who works for Toro said that it is no mistake they are building cheap crappy quality gas lawn equipment. They are doing this to push consumers into buying battery powered equipment. Well I say it is sad because men like Taryl have a wealth of knowledge that is being shoved to the curb because of this. Regardless I appreciate all those who've stuck it out in this business and hope they continue to as people are finally pushing back. Thank you Taryl and crew.
I have the 2 stroke BR340 It’s always since the day I bought it nothing but a pain to get it started 2 shops no luck so I just went out and husquvarna 150 BP starts every time 2 pulls
I rebuilt my dads 4 stroke Honda GX35 powered line trimmer 4 years ago because it had a blob of carbon on the inlet valve which stopped it from running,I just cleaned up the valves & reassembled it. I repaired the same flywheel key problem in his neighbours 2 stroke.McCulloch leaf blower but I used a hacksaw blade to cut a new keyway out of the aluminium flywheel then I made my own key out of key steel. I have had a car engine which was surging & stalling at an intersection in a car that I bought 22 years ago & it was a bad rear main oil seal which caused the problem,it was due to a crankcase air leak & I have also had a similar experience in my current car due to a leaky front crankshaft oil seal, replacing the seal made the engine a bit more powerful. I know that my old manager Ray who passed away 5 years ago was against gluing mechanical parts together (power tools) although he used it within the constraints for what it's designed for. So he wasn't a Walmsley who would use half a bottle of Loctite to fill a bearing housing which had as 0.5mm or 0.020" clearance when all it was good for us a 0.2mm or 0.008" clearance !
I don't work on ANY small engines at all but it is nice that there are people out there who know things. Things that by all rights should be _in the service manuals_ but for some reason are not. You ever said it yourself that these problems are very common with these so it is would only make it right if they put these in there so we can get them working. Instead that customer you just helped was probably ready to throw the thing away! I know I probably would have! I would have washed my hands of that thing once and for all throwing it out!
As a itinerate lifelong tinkerer/mechanic I really enjoy your videos. I’m sure you probably already know this but I’ll mention this anyway- I saw on your Stihl blower repair your dewalt 18vt nicad were dying I had the same problem and dewalt then came out with 20vt lithium battery tools. I went on Amazon and found a lithium battery that fits the 18vt dewalt tools and dewalt makes an adapter to fit their 20vt lithium battery in their 18vt tools. Great video on the Stihl blower… wanna buy a couple Stihl tools of destruction?
Thx Taryl for all the helpful suggestions. I bought one of these because it’s comfortable and has excellent power and it does run smooth and fires on the first pull. I’ll keep a eye on things if anything goes wrong and just fix it myself and stay away from the dealers that have monkeys work on my equipment. Car dealers are no better because I worked from them for over 30 years and saw a lot of 🙈🙉🙊MONKEYS! Two strokes are nice but I wanted to give a Stihl fourmix a try 😊
I never really liked the 800 C-E. I never liked the side start feature. I am not saying that it is a bad machine but I still stick to my older and trusted BR 600 Magnum which starts first or second pull since 2015. It also brings the power to the point because of the tube, which is nice when you want to blow away gravel and other stuff. If I would need a bigger blower I might take a look at Echo, RedMax or Shindaiwa. They have pure two-stroke engines no Valves etc. and I think the quality is better.
So after watching I did get a few good take aways:
1- 50PSI is not too low for the machine to start.
2- Using a tap holder to lap the valves is so simple that its genius!
3-The guy that commented that this "big" blower is putting tons of carbon in the atmosphere is watching the wrong channel.
4- Junior is a good drummer 🎉
5-And lastly, Taryl should watch videos from a guy on UA-cam called "Taryl Fixes All". More than once have I have heard and seen Taryl say we need 3 things to make an engine run. Fuel, Spark, and Com-presh-yee-own. He also says the timing of the spark is important.

Use a sharpie pin on the valve face and turn it again and then you can see if it is seated all around.

I like to do a leakdown test before I tare engines down. Because if you miss 1 simple thing before the tare down the you run into a fog when nothing seems wrong internally.
Yep.
I wish I had the patience like Taryl...I like to learn but give up to much...I really do try...I learn so much from him....
Hey Taryl this is an awesome breakdown tutorial. I moved away from a lot of 2 cycle handheld repairs and limit what I do. The flywheel on these units should be redesigned.
Excellent video
Its obvioua that they are designing them to fail, with all the materials science they cant produce a reliable product? Ive noticed the brands bosch, stihl and bmw ,merch have flashy products that just do not last. It all started with the mobius cartel in the 20s and 30s where light globes were made to fail.such a waste of resources and energy,there is nothing wrong with making business, but engineered obsolescence is undemocratic .
Glad I went with the 600! Never failed to start cold after 2nd pull!
That brother of yours is a genius.
Good fix Taryl, you are a jet-pack scientist to repair that 4-mix!!
What a valuable video!
Because I have the 800c.
Now I know all about it. Thank you, Taryl
I have a brush cutter that was hard to start when hot, I thought it was the carb but it was the gap between the coil pick ups and the magnets was too great.
When it was hot the gap widened and spark was weak.
Did the business card fix and wala it works great.
love the show! thanks!
nice job terral
Had the same problem. I used a round file and notched the flywheel to accept a piece of drill stock. Haven’t had any problems since.
Good idea!
When I was looking at a new trimmer I seen those 4-mix things. Decided piss on that, if I'm going to have to worry about valves and still mix fuel they could keep it.
I own a 25 year old Husqvarna back pack blower. It always was a cold one starting in the Winter.
Always starts fine in the warmer weather. It is still running and all I have ever done is change plug, fuel filter, fuel lines, and some wiring repairs. Good piece of equipment.
Good learning curve,This small stuff can be a real challenge,great job
Junior and I have that one thing in common, drums are a big part of my life I started when I was 16 and kept it up ever since I'm 26 now, it's a great hobby,❤
I have amazing respect for your knowledge, experience, skill, and humor. Have a Hamm's or two! Thanks, Taryl.
I learned something new today the 4mix are all p.o.f I will stick with my old BR400 because it was made when Stihl and Echo were equal in quality. Good video Taryl.
What about the Yellow wire? You said during reassembly you would talk about that, or did I miss that? Great video again.
Guess He Forgot...Musta'-Had Too-Many HAMMS🍺🍺🍺🍺🍺🍺🍺During Them POTTY-BREAKs🤥💦🚽
31:00. Great idea to use a tap wrench to lap valves from the other side! 👍
I just took apart a br600 that ate a exhaust valve. Broke at the stem. Good timing on the video. Thanks
The blower has a 2 year warrantee? That is why I like Echo they have 5 year warrantee
You are good teacher. I have learned a lot from you also entertaining. Keep up the good work you do.👍
Fantastic job 🎉 You are amazing Tareyl . Thank you for what you do .
Thank you for showing all of the neat techniques you found in repairing this machine. A lot of the newer equipment is junk when I purchase it. I have a Craftsman edger that is almost thirty years old. It runs good. I have to lap and adjust the valves once.
Bought a new McLane edger July of 1980. Briggs engine, still runs like new, 44 years old. Still has the original spark plug. Just use straight 30W oil, change every year, keep the air filter clean, and they'll run forever. Have replaced the blade probably 15 or 20 times, but that's it.
That was a very good investigation video, you wouldn’t think 4 cycle would have the pressure issue of the 2 cycle, like the old saying says you learn something new everyday! Thanks for going over this piece of equipment great video👍
I own an Echo PB 9010. A beast of a blower! My one complaint is the wimpy detent on the cruise control. You slide the lever from full throttle to idle and you overshoot idle turning the engine off. Take the unit off your back and restart. Pain in the arse! I found that holding the throttle while moving the lever back helps avoid the overshoot, but, I now avoid the cruise control.
I was going to upgrade my gas blower this year, but then in Portland Oregon they just banned Gas Blowers. Weird, I still see even the city still use them. But ban them for residential users.
Go to work at the city, then have them help you get one. If you're good enough, they'll probably help you out. I did that once here, lol. If it has the city's metal tag, they can't keep you from owning it if you got it legally. 😮
That isn't right, another freedom gone.
@@davidpotter9462 👆 I like this guy!
I bought a parts br800 that ended up having a loose flywheel with a sheared key, I just cut a slot in the flywheel with a thin metal cutting saw blade and created a key from metal stock, and off it goes!!
I bought one of those and I was so pissed off at it because it was the same type of thing I had going on it would not start and I finally went back to a smaller blower because of this problem. Honestly the small one works just fine for me.
nice one , this one had a curve ball repair , Very well done on the end result, love these fault findings
31:58 “You’re looking at a psychopath”. LOLOLOL! Got me laughing hard on THAT one, Taryl! 🙏👍
Great video Taryl. I have a Makita 4-Stroke no mix Backpack Blower Love it, works great!
I have two of these blowers, one for over ten years with at least weekly use. The other is identical to the one in this video. NEVER a problem. I love them. I use non-ethanol gasoline in all my lawn equipment and synthetic 2 stroke oil.
Old equipment is better sometimes. Great video 💯💯
I had a chain saw that had to have the crankshaft seals replaced. More work than I wanted, but the saw ran great.
Great job Taryl!
Wow, loose flywheel and bad crank seals and questionable ex. Valve!!!!
I made a key out of jb weld and it worked perfectly
Excellent episode, Taryl!! Thanks so much !!!!
Taryl - I was surprised when you said the piston pin bushing is not replaceable and you need to buy a new crank if you were going to fix it. In Australia for many years the Victa Mower 2 stroke 125cc and early 160cc mower engines had a brass bushing for the gudgeon pin. We would use a home made draw bolt using an undersize socket or pipe to pull the bush out. or set up a vise and press with pipes and or sockets. They was a replacement part but also there was brass or bronze bushings of different sizes that you could buy from engineering shops. Once you cut the length needed, fit it in the small end, by squashing it in with the vise, we then used a reamer and cut in until the piston pin ran smoothly through without any binding. It wasn't a big deal back then and the bushing lasted for many years. That exercise may take roughly 30mins to do. The reaming was done slowly which took a bit time. The point is, its repairable , if you could be bothered to pull it all down. The labour time makes it all beyond economical repair and no dealer I know would do it these days with their charge out rates. Like you point out why not use a needle roller in the gudgeon in the first place. Thanks Stihl.
I have used J B weld in the past instead of Thread Locket ,worked well just have to let it set 24 hours after the nut is torqued.
Check the coil gap, may need to reset coil gap!
I have 2 of the exact same blowers...Possibly the strongest blower on the market today. Our blowers start fine on usually the third pull. We use Stihl HP Ultra premix and run the machines hard..these things don't want to be at half throttle. JMHO
I know you know this but! 1st thing is check Stihl for a service bulletin for this problem. If none then check to see if it really is hard to start by putting some fuel into cylinder bore and then pull it over. If it starts right up you have a fuel delivery issue and you know the spark is good. If not it is the timing, valves or piston rings. Broken flywheel keys are common. Check that first. Glad you solved it.
You forgot about the seals already?
Thanks for all that great information. Koodos to you Taryl..
I watch a lot of videos on still equipment like chainsaws and blowers always have lot of problems ring stickin And pistons getting scored
I bought a stihl pressure washer a year ago. I’ve only used the pof a few times and it’s already in a repair shop
Great job on that repair can’t believe the dealer it went to could not figure it out and that sounds odd they probably just didn’t want to work on it…👍👍
THEY DON'T CARE, SELL ONCE TO A DUNCE.
Hey Taryl! Thank you for sharing this video! I have been thinking about getting one of those Stilch backpack blowers for a few years now. Really glad I put it off. Mulching leaves is much better in my opinion. You don't have a clean up a huge pile after using a blower. Thanks again Taryl! Keep the videos and skits coming!!
Out value the machine fixing those,thumbs up great video
Another job well hammered, Brill.
Nice diagnosis! Nothing is easy
thankyou to taryl . for always finding out manufactures defects. he is one top notch person. thanks for showing us..
Great video Taryl. I noticed your work bench was cleaned right away. Your entire shop is looking really good.
Good work Taryl!
Ive worked on the echo backpacks and had no problems , and I'm a STIHL man . I think I'LL stay from from the STIHL backpacks after watching this . WOW
I’m literally addicted…. But I like to save money and do things myself. Thank you so very much! Love me some Taryl ! And his brother! Great job ! 😊
Thank you Taryl.
Did you put locktight on the flywheel bolt....did didn't see.. just checking cause it will work loose I believe..thanks
I still have a stihl feeler guage for adjusting the valve clearance. seems like the clearance is or was .002. not .010. I remember the clearance was fairly critical
Excellent work.regards from Australia
Loctite press fit 648 i believe, few other flavors would be ideal for a situation like that flywheel.
Great video-True knowledge-Thanks
When I see these kind of videos where they're being repaired.It's proof that you did a great job
Excellent diagnosis, great video Taryl and co. Learned something there.👍
It has an easy start, when on back you pull cord halfway lightly than let it go back than pull forward lightly but quickly and it will start, I also learned that you can remove the side start and install the normal pull robe on back if you want
Honestly would love to sit down and chat with Taryl and his friends. They seem to have a real chemistry which reminds me back in the day when friends use to love sitting around and cutting up for laughs. They remind me of an old show I used to watch called the Big Chuck Little John show that hosted movies on the weekend. I am greatful for Taryls knowledge he has shared and his good natured comedic life. It saddens me that the gov is shoving this green deal crap and what angers me is a friend I have known for years who works for Toro said that it is no mistake they are building cheap crappy quality gas lawn equipment. They are doing this to push consumers into buying battery powered equipment. Well I say it is sad because men like Taryl have a wealth of knowledge that is being shoved to the curb because of this. Regardless I appreciate all those who've stuck it out in this business and hope they continue to as people are finally pushing back. Thank you Taryl and crew.
I have the 2 stroke BR340
It’s always since the day I bought it nothing but a pain to get it started 2 shops no luck so I just went out and husquvarna 150 BP starts every time 2 pulls
Brilliant! Thanks!
Thank you for helping us
Thanks for sharing information and advice ❤
I rebuilt my dads 4 stroke Honda GX35 powered line trimmer 4 years ago because it had a blob of carbon on the inlet valve which stopped it from running,I just cleaned up the valves & reassembled it.
I repaired the same flywheel key problem in his neighbours 2 stroke.McCulloch leaf blower but I used a hacksaw blade to cut a new keyway out of the aluminium flywheel then I made my own key out of key steel.
I have had a car engine which was surging & stalling at an intersection in a car that I bought 22 years ago & it was a bad rear main oil seal which caused the problem,it was due to a crankcase air leak & I have also had a similar experience in my current car due to a leaky front crankshaft oil seal, replacing the seal made the engine a bit more powerful.
I know that my old manager Ray who passed away 5 years ago was against gluing mechanical parts together (power tools) although he used it within the constraints for what it's designed for.
So he wasn't a Walmsley who would use half a bottle of Loctite to fill a bearing housing which had as 0.5mm or 0.020" clearance when all it was good for us a 0.2mm or 0.008" clearance !
I don't work on ANY small engines at all but it is nice that there are people out there who know things. Things that by all rights should be _in the service manuals_ but for some reason are not. You ever said it yourself that these problems are very common with these so it is would only make it right if they put these in there so we can get them working. Instead that customer you just helped was probably ready to throw the thing away! I know I probably would have! I would have washed my hands of that thing once and for all throwing it out!
As a itinerate lifelong tinkerer/mechanic I really enjoy your videos. I’m sure you probably already know this but I’ll mention this anyway- I saw on your Stihl blower repair your dewalt 18vt nicad were dying I had the same problem and dewalt then came out with 20vt lithium battery tools. I went on Amazon and found a lithium battery that fits the 18vt dewalt tools and dewalt makes an adapter to fit their 20vt lithium battery in their 18vt tools. Great video on the Stihl blower… wanna buy a couple Stihl tools of destruction?
Thx Taryl for all the helpful suggestions. I bought one of these because it’s comfortable and has excellent power and it does run smooth and fires on the first pull. I’ll keep a eye on things if anything goes wrong and just fix it myself and stay away from the dealers that have monkeys work on my equipment. Car dealers are no better because I worked from them for over 30 years and saw a lot of 🙈🙉🙊MONKEYS! Two strokes are nice but I wanted to give a Stihl fourmix a try 😊
Unbelievable. Crazy skills
I never really liked the 800 C-E. I never liked the side start feature. I am not saying that it is a bad machine but I still stick to my older and trusted BR 600 Magnum which starts first or second pull since 2015. It also brings the power to the point because of the tube, which is nice when you want to blow away gravel and other stuff.
If I would need a bigger blower I might take a look at Echo, RedMax or Shindaiwa. They have pure two-stroke engines no Valves etc. and I think the quality is better.
So would you recommend checking the flywheel nut as a routine PM on this blower?
Great information. Great video. Thanks
Great informational video , I never heard of an engine like that . Wonder what the advantages are .
The advantage is the manufacturer doesn't have to pay a fine.
Taryl where did you get the yellow hose clamp for fuel lines.
Got some good information on working on Stihl.
I repair small engines for friends.
