very easy to understand how you repaired the leaf blower...Thank you

[@susanford9556]

I fixed my Stihl string trimmer using one of your KZbin 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

[@acreguy3156]

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!!

[@curious-homebody]

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.

[@aleblanc3547]

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.

[@proflondonuk]

Typically happens when crank case seals are leaking. Not a difficult job but you have to dismantle the engine completely to fix it. Search KZbin and it'll show how to do it....

[@aleblanc3547]

@@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.

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?

[@JH-fv1gq]

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. ..?

[@Athonite]

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).

[@apatterson8128]

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!

[@shakey2634]

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.

[@tomhism]

Make sure to dip the spark plug in oil first before starting.

[@christopherness81]

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?

[@donyboy73]

i favor the richer side, less chance of intake scoring on piston

[@kevina4674]

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.

[@zx8401ztv]

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.

[@donyboy73]

and also viewers watching can easily replace a carb themselves watching this video

[@B.Arnold-22964]

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!

[@robertfuqua-i5b]

[@my2cents108]

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?

[@DH-mf2lv]

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.

[@deannadler9917]

Best thing would be get an Echo!!

[@mikenco]

I got a blower with this exact problem. What is the issue with the carb, are they not serviceable?

[@bobkucharski9425]

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,

[@rudolphvarshine1606]

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

[@bentullett6068]

I don't trust anything parts wise sold on Amazon or Ebay so I agree with you always fit genuine carburettors or parts.

[@WJHandyDad]

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.

[@K3rm1tFr0g]

Good video. Good channel

[@seanperdue232]

So what part or section of the original carb stopped working properly?

[@bigbob0042]

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

[@motox570]

bigbob0042 same here. I used to use them quite often with good results. Last 10 I got 8 were bad. No more.

[@BarnyardEngineering]

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.

[@BkLiveWire]

I got an older ECHO blower (PB 200 2005 or 2006 era) working but I noticed it was smoking for awhile after I got it running. Is that normal if it’s been sitting for years? It did stop after about 3-5 mins though.

[@JM-zz5mh]

Is swapping the carb really a FIX?

[@bentullett6068]

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.

[@michaeljolly1908]

Adjust the high/ low on carb…simple fix

[@TheRastler]

Stay away from Stihl carbs get a carb with fully adjustable jets.

[@ellelephant]

Could have made 3 second video that stated ‘buy a new carb the same price as another used stihl blower’

[@donyboy73]

I only use stihl oem carbs on other people's equipment

[@unfundedopportunities7278]

Don, I salvaged a 2001 Ryobi 31cc leaf blower - another victim of ethanol poisoning. It starts and runs fine, but it doesn't seem push leaves very well. It does better with the nozzle removed. Is this normal for these small hand-held units? The exhaust is clear, and the piston and cylinder look great. I can get more done with a bamboo rake. This my first experience with a gas leaf blower.

[@donyboy73]

they are not as good as backpack blowers but you may have low compression and they are not the best units either

[@bradstanley1493]

Hey buddy, I have the exact same model and I mixed a fresh can of fuel 92-non-ethanol and the proper oil mix and it doesn’t want to run on full power it keeps bogging down and will only stay running on 1/2 choke? I checked the spark arrestor and it was clean and so was the plug ..? 🤷🏼 Have any ideas? Your feedback would be graciously appreciated 👍

sometimes turning out the L and H screws cures it

[@rogeliopadilla1432]

Thank's very very muuuuuch. 😁👍

[@09hoseclamp]

What is the expected compression on a handheld leaf blower if you suspect worn rings?

[@spiercevaughn]

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.

[@scottfirman]

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.

[@Urbicide]

Zama carburetors are made in China. I believe that Stihl either owns Zama outright, or owns a large controlling interest in the company.

[@scottfirman]

@@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.

[@bentullett6068]

Find out from a Stihl dealer first. You may want to remove the carburettor as they have made various different carburettors and their is a code engraved on the metal main carburettor section, usually a letter followed by some numbers and another letter.

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
