Easy to follow and thorough step by step tutorials do it yourself (DIY) to help you with your broken lawn and garden equipment including snowblowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed wacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on TH-cam and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!
I want "DON THE SMALL ENGINE DOCTOR" on TH-cam to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

Yeah, he's really good, isn't he? Even more extraordinary for someone whose profession is not video production.
@@ianbutler1983
Agreed.
So many videos have all kinds of background noise, shaky camera work or annoying background music.
These are a pleasure to watch and easy to understand.
Damn good mechanic too!
I agree, an excellent tutorial!
Excellent. You should make a video on how to make a video.
Glad someone mentioned the inconsistency of aftermarket carbs.
LOL , ive been saying it for years and when i do its like a bunch of people in the comments on videos and forums want to fight me or something and say im full of shit , them saying thats all they use is aftermarket carbs and have never had an issue, and my reply is always the same , well i guess im not as lucky as you LOL
@@bigbob0042 the fact is some customers may not complain but will never come back
I always rebuild an OEM carb.
Same here
Al's Repair and Restoration If the check valve is bad the carb won’t work right no matter what you do.
Thanks, Don!!! My SH-55 starts fine. When I rev it up, it achieves full RPMs but then drops about 25%. If I trigger it a few times, it returns to full RPMs and then dies again. I checked the spark arrester screen and it's fine. I'll by a new carb. There's a Stihl dealer just down the street. Thanks again!!
I fixed my Stihl string trimmer using one of your TH-cam videos. Now, I feel confident that I can fix my leaf blower. You are the easiest to follow, of anyone that produces instructional repair videos, on the internet. Thanks
very easy to understand how you repaired the leaf blower...Thank you
i really like how much you stress about hand torquing. i've encountered many tools with broken or stripped out mount holes from other repair guys. i've ordered many tool and tool casing replacements in the past as a result. thank you for what you do.
Power tools have no place on 2 cly engine repair 😊
I just finished doing the same thing to the exact leafblower i bought at a yard sale for $20. Old guy had it for a week it was still in box he said he used once went to use again and it wouldnt rev up replaced carb and runs awesome. Love the channel
you ARE a freaking boss
Finally someone who posted a helpful video. Awesome!!!
Best advice on using oem replacement parts. The Chainsaw Guy told me the same thing when I just ended up replacing my friends carb on his Stihl weed eater. Your time is worth just fixing it once.
Used your video to replace carb on my stihl blower. Worked like a charm. Thx. Fabulous guidance.
Always a pleasure to see you work. Greetings from Holland.
in 2000 I was in Holland for 2 weeks
Your videos have saved me trips and time at the repair shop, Tks.
ALWAYS USE HIGH OCTANE FUEL WITH NO ETHANOL TO PREVENT DAMAGE AND COSTLY CARBURETOR REPAIRS ON YOUR OUTDOOR POWER EQUIPMENT!
Man this was a awesome video. Short and to the point. Thank you
Excellent video on Stihl carb replacement. DonyBoy was careful to mention the possibility of a clogged/fouled spark arrestor causing the motor to bod down. It will in fact, I've experienced that problem. thanks to his attention to detail!
Great video this assisted me greatly. You are a real pro and excellent instructor for lay poeple like me.
Another clear, concise, superbly done video . Thank you again for taking the time to help others learn. 👍
Beautifully done sir. Very detailed. You saved me by identifying the screws. I was lost thought they were alike when I removed them. Thing wasn't lining up. Glad I found you. Thanks alot!
Thanks Danny for this video! Your videos are always very detailed and easy to follow! Also, you always provide the part numbers for any part or toll that you are using! That is very considerate of you!
A perfect service presentation! Always useful and easy to watch! Thank you for your help! Best regards from Athens, Greece.
Thank you so much! I thought I was gonna have a take it in for servicing or purchase a new one. Now it runs stronger than ever! I just changed the spark plug and cleaned the spark arrestor which was totally clogged. Checked the air filter and it was still in good shape.
I agree on stihl products use stihl carbs. Thanks for sharing donyboy. Hope you wife is doing well. Have a great weekend!!!
thanks
Great video. I always worry about after market carbs, but some people don't want to spend or have the money for OEM carbs.
Simply the best small engine man on youtube.
I've got the BG-50 that usually takes about 5 - 6 pulls to get it going, but after it's warmed up it's almost impossible to restart. It hasn't been an issue because once I get it going it runs well until the job's done. I am going to turn out the high and low speed screws a bit more to see if that improves starting both when cold and once it gets warm. Great machine regardless. Thanks Don.
Typically happens when crank case seals are leaking. Not a difficult job but you have to dismantle the engine completely to fix it. Search TH-cam and it'll show how to do it....
@@proflondonuk Thanks, bud! It's a problem that existed even when the blower was new, which doesn't mean it can't still be the problem due to manufacturing irregularities, but I'm hoping it boils down a simple carb adjustment.
@@aleblanc3547 Did the carb adjust help the problem?
@@bounjamin Sadly I gave it away before I tried the carb adjustment and bought an EGO.
I’m having the same issue.
Your very knowledgeable. I learn something new every time when I watch your videos. Thanks for all the videos
I'm not especially handyut was able to replace the carb on my BG55 Stihl following your well done directions. With a new spark plug and filter also added it runs better than the day I bought it in 2014.
Your videos are always a pleasure to watch, you make it all look easy.
Thank you! Cheers!
Fantastic video. You make it look so easy. I could turn that job into two or three day event. Thank you for the video.
Thanks Donyboy. I did everything on a trash find husqvarna 225b and still bogs. New carb on the way.
Thank you for the video! Great explanation and quite easy to understand :)
You are the best at showing how to repair small engines, thanks for letting us look iver your shoulder!
OUTSTANDING !!, DB73, I never tire of learning about small engines and the mechanics of them. Thanks Man !!! Cheers !!***..
Good job Don
Great advise there my canadian brother cheap after market carbs aren't worth the money or the time
Milwaukee’s M12 Fuel ratchets would be very useful in your line of work. They have plenty of torque and are very well made/ well designed overall. I have the 3/8 drive myself and it works wonders. Let the machines do the leg work.
Man I miss them days when you could just use a carb kit and be good shops are so quick to replace stuff
I will tell you one more thing that sometimes happens to these... you will here a zing and it will shut off... normally someone would think who put straight gas in this it’s now seized!!! But it sometimes turns out to be one of the three screws behind the fly wheel. One of them came too loose and blocked the wheel from spinning! Happened on two different stihls of mine. The bg86c I believe.
Fantastic video mate. Yeah some of the copy carbs are a bit hit and miss. Good fix
The customer will be happy :-D
I remember your advice from a year or two back, cleaning doesn't always fix it so don't waste any more time, replace the carb with a new one, that is the fix.
I think it was for a square chain saw carb, same nasty design i think.
and also viewers watching can easily replace a carb themselves watching this video
Very well explained Donny thankyou
Thank you. You are a very good teacher 🤛.
Make sure to dip the spark plug in oil first before starting.
Good job! Saved me a trip to dealer!
good video as usual thanks
Fantastic video! Thanks for sharing.
Great video dony
Excellent information, thank you.
So many carb problems on expensive equipment it seems. My strimmer, hedgecutter and a blower were bought in 1990. Never touched the carbs always start easy and run well.
Original air and fuel filters too. All I do is run them dry before winter shutdown. ..?
Cherish your older gear! Newer models have been tampered with by the EPA here in the states. The default carb settings are for emissions, not performance, and they require the manufacturer to place a block on the adjustment screws of the carb. Even our fuel cans are required to be defective (no vents and a crappy spout).
After 25 years, I finally have to rebuild my Echo's SRM-2400's carb. It doesn't owe me a thing. If rebuilding it doesn't work, I'm going to buy an OEM carb. Can't beat that old gear!
Donyboy you're the man love watching your video's
First class video as always. Thanks again Dony.
Best thing would be get an Echo!!
Great stuff, brilliantly done...
Did you check, replace the fuel filter before going with the carb? My own experience is I clean the spark arrestor about three times to fix a bog down issue, then the fourth time it’s the fuel filter.
Thanks for all the great information!
Part Numbers, are a great addition to this video. On the Tools you used Zero's, On the Carb Oh's, Is that the case?
once again thank-you!
I have the exact same one. I may end up replacing the carburetor on mine also. It runs best partially choked so I think the diaphragm may be getting weak. This is a good video to show how to disassemble it. I find its better to just replace the carburetor anyways. Those cheap Chinese carburetors are NOT worth the money you spend. They go bad in a year.
Zama carburetors are made in China. I believe that Stihl either owns Zama outright, or owns a large controlling interest in the company.
@@Urbicide Because of that, they may have a better control on quality. Aftermarket replacement parts are usually seconds or those that didn't pass a quality control check. Others are surplus made fo r someone that went under and are extra stock. They get resold on E-bay. You do not know who they are made for unless they have Zama or another Manufacter stamped on them. This is common practice in China.
Epic video Dony
Stay away from Stihl carbs get a carb with fully adjustable jets.
Good job donnie
Thanks for the good information.
Stihl dealers tell me no such thing as an OEM carb or rebuild kit. Have to buy a whole new saw/blower/trimmer. Cheap Ebay carbs have been a Godsend.
I don't trust anything parts wise sold on Amazon or Ebay so I agree with you always fit genuine carburettors or parts.
Question: At 8:31 you say to remove the muffler to check for piston and ring scoring. Do you have a video for this? Thanks.
i had a similar problem with my stihl leaf blower. i torched the spark arrestor clean. same problem. i cleaned the air filter. same problem. i boughtt a stihl maintenance kit for it. i replaced the air filter. voila! all is good.
Great video. I have a BG85. Will this carburetor work or will I need a different part number for a Stihl carburetor? Thanks in advance.
I agree with you completely, i dont mess with those ebay, amazon cheapo carbs anymore either, maybe 2 out of 10 worked right, i dont even give the customer that option anymore cause i got tired of seeing them come back
bigbob0042 same here. I used to use them quite often with good results. Last 10 I got 8 were bad. No more.
Hey Dony I have one that Ive done all this youve done but Im now thinking its the cheap carburetor if i lean it to one way it slows down which is strange have you ever had one do this? Once its hot tho it seems to do ok I guess..Anyway give me any thoughts please.Thanks!
Thanks for great video. Will this carb work for the Stihl BG 56 blower? If not, what is the model number for that blower. I am getting different numbers on websites...
So even after you repaired the carb, it still didn't work...humm. After reading a few other comments, I was initially expecting to see what "bogged" down the engine. But you just replaced the carb and that was that. Not what I was expecting to see. I mean what was the real cause of the "bog" so others can check their blowers when they experience such a problem? That is what I was wanting to see... JMHO
good video. great edits and close up shots. great tips for this repair!
I got a blower with this exact problem. What is the issue with the carb, are they not serviceable?
I just put a new carbatraitor and mufkin on mine.....
any idea why leaf blowers are so prone to failure? I typically get 1-3 seasons with a leaf blower before it seems to be unfixable (I've tried everything other than a full carb replacement) whereas I get 10+ years problem free with string trimmers, edgers, and other gas powered stuff just by changing spark plug annually. I do run ethanol free gas whenever I can.
So what part or section of the original carb stopped working properly?
Great video, thank you - it’s running like new!
Cheers
My bg 85 runs good but when I try to adjust the high screw nothing happens it still runs the same what is wrong thank you ted varshine
On a new Stihl carb are the limiter caps just resting on the H and L needles or fully installed? After tuning how do you set the limiters? Half way to get equal adjustment or do you favour the richer side with more adjustment?
i favor the richer side, less chance of intake scoring on piston
Hi dony, thanks for the video, I'm surprised to see you don't have more subscribers, 🤔
it's because I don't make sensational titles
I have a 6 year old Stihl BG 86. It barely starts and will only run on half choke, when I throttle it dies. I use nonethanol gas. This is what I've done so far with no success, same problem with no changes:
Checked spark plug, checked the air filter, checked the spark arrestor and mufler, replaced the carburetor, fuel lines and filter. Final item, replaced the tank vent.
I'm puzzled as what to do next, any help/suggestions would be great appreciated,
Is swapping the carb really a FIX?
Sometimes it can be because some of these new carburettors have hidden gauze's inside them that have purposely be made to not be replaced or be cleaned properly.
I swear I was subscribed to you but TH-cam unsubscribed me. Resubbed!
I need your help. I own a Stihl BR380 that has very few hours of use. Last week (while running it full throttle for 25-30 minutes) it started to bog down. I dropped the throttle back to idle and it ran perfectly. I increased back to full throttle and after a few seconds it did the same thing. I verified the spark arrestor was clean, verified the air filter was clean, verified the gas filter was clean, replaced the spark plug (old one looked normal), also when it started losing RPM I took off the gas tank cap to see if that would help. I am at a loss. When cold, it starts up like it always has. Couple of pulls. I use only nonethanol fuel and Bel-Ray full synthetic 2-stroke oil. Your thoughts? Any suggestion(s) will be greatly appreciated.
Mine never revved up properly.. less than 2 years old.. spark arrestir is clean. Dealer says it’s ok .. I get more blowing power from my battery blower.
Could have made 3 second video that stated ‘buy a new carb the same price as another used stihl blower’
Don, are concentrator nozzles really needed on hand-held units to create back pressure (load) for the motor? Do backpack models have them, or need them?
Is it possible to fix a rusted cylinder on a weedeater?
If the OE carb is the problem why replace it with same?
Adjust the high/ low on carb…simple fix
Good video. Good channel
What's with that HUGE ultrasonic cleaner box Dony? Always enjoy your channel, thanks for all the work you put into it
a review is on its way
Thank's very very muuuuuch. 😁👍
What’s wrong with the carb where it needs replacement?
How much is that carb from Stihl...list price?.Thanks
Hi Dony, cant they be well cleaned inside?
Ops, just saw the answer in the comments
do you also recomend to by original carburator for Tecumseh motors on snowblowers
some aftermarket carbs are good like in this video, th-cam.com/video/elsP-Sp62z4/w-d-xo.html
What is the expected compression on a handheld leaf blower if you suspect worn rings?
09hoseclamp theres not a number you can just expect. It will depend on how worn the rings are, or what causes it to wear in the first place, and how long they have been wearing at an accelerated rate due to damage in the first place. You can get a compression tested for fairly inexpensive online or rent on from a auto parts store.
