Stihl weed eater bogging. It's NOT your carb!

3 years after this video is made, it's still saving people money. I did this and now my weed eater starts on one pull and runs like new. Thank you!

[@Recovering_Californian]

Took apart my STIHL trimmer after it started to bog down. Didn't find anything mechanically wrong with it. Was about to take off carb and clean it when I ran across this video. Removed the screen and that was the problem. It was nearly 100% blocked. Thank you!!

[@mikechafin7351]

Spot on! My neighbor brought his trimmer over last night. It would start but then die. I found he forgot to mix in the 2 cycle oil on the last fill up. Once we sorted that out it ran but sounded terrible and bogged down when you hit the trigger. I was worried it might have scored the cylinder from lack of lubrication, but it looked fine with my cheap boroscope. All I could think of was to rebuild the carb, but found your video this morning. As soon as I heard the sound yours made I knew it was the same issue. Sure enough, the spark arrestor was completely clogged. Cleaned the screen and all is well! Thank you for posting this video.

[@TepcoCycleRepair]

It happens quite a bit. I just fixed a 4 stroke generator with the same issue so it's not only 2 strokes. I'm guessing it's the quality of fuel available today.

[@marshallborder9089]

I've fixed this problems many a times , I was told too always re install it too . Spark arrester is there for a reason . Great video

[@EarlGuyton425]

Those screens arent there for any reason and should be removed or on some simply punch them out with a screwdriver

[@shawndubay4050]

Good fix. I generally take the muffler off and then I'll take a mapp gas torch and heat up the whole muffler inside and out until it glows orange, let cool and reinstall it. All carbon burnt to dust. Generally they run good as new or better.

[@TepcoCycleRepair]

That works great as well!

[@kgt9535]

Great tip bro...thanks. I think my 4 mix has the the same that that 2 stroke had. When cold, mine hesitates to rev up fully until its warm and still here and there after it's all warned up it bogs down and then revs as it should randomly. I'm gonna check the exhaust screen...I have an fs91r.

[@TepcoCycleRepair]

@@kgt9535 Do that and check the valves, I have a video on that as well. They're easy to do you just need a special feeler gauge to fit.

[@LordDeadSpider]

Fighting with this issue with my FS90r. Screen was clear. I will try to loosen up the exhaust itself and see if that helps. I’ll try it tomorrow, just locked the weedwacker up for the night out of frustration.

[@forrestaustin7050]

What did you clean it up with ...

[@TepcoCycleRepair]

Just a wire brush, tapped it with the bristles to clean the holes in the screen. Then some brake cleaner.

[@samwells1862]

Thank you, da man nailed it, exactly what mine was running

you shouldn't have removed entire exhaust, just the screen

[@cas2985]

This guy doesn’t seem to know what he’s doing.

[@TepcoCycleRepair]

I loosened the exhaust for diagnosis. You should remove the entire exhaust to be sure it's not clogged beyond the screen. I have seen some pretty heavy carbon buildup inside the exhaust itself. I prefer to do a thorough job to prevent a returning customer.

[@jesusloya6462]

I can confirm. I only removed the screen and the problem persisted. After watching the video, I loosened up the muffler like he did and walah. You could definitely feel the difference in power. I now know I have to clean my muffler

[@KevinBrown-em3ng]

Thanks so much that’s exactly what was wrong with mine so freaking helpful !!!!

[@jamesgerrond4770]

Bang on!!!!! wish I seen this 3 hrs ago.

[@crasher88]

what would be the next step after you did this and still bogs down

[@TepcoCycleRepair]

Replace the diaphragm, but honestly I would just get a Amazon carb from like HIPA . It will be cheaper and easier and if it doesn't work just send it back. Reason I say that is there are one way valves in the block carb that if they got messed up you won't know, you can't replace them and you'll spend money and time rebuilding and it still won't work right. Crazy world we live in, when a new carb is cheaper.

[@garny3766]

Yup them damn spark arrestors. Some are a flat screen some are like a spark plug.

[@markboulter5714]

Awesome thing to keep in mind before you jump in to everything else because if that is the problem you will still get same results un till you check it out thanks

[@icuformiles420]

Thanks so much you are awesome really appreciate the video

[@mrderlight]

What if the spark arrester is missing and it's bogging down?

[@TepcoCycleRepair]

Then it's the carb, usually the diaphragm dries out and can't keep up with the fuel needed, or the ports get clogged and the fuel can't flow.

[@dope7kids]

Why doesn't Sthil just include 5 of the spark arrestor screens when they sell you the snipper.?

[@TepcoCycleRepair]

They're easy enough to clean. Make it part of your maintenance and it will never clog

[@plugtheheliflyer]

petrol strimmer bogs down could it be the exhaust I've cleaned the filter in mine. New carburettor new air filter new spark plug and fresh petrol and new oil. Still bogs down when adding throttle.

[@TepcoCycleRepair]

The exhaust itself could be clogged but if the carb is adjustable it may just need adjustments. They usually fit many different engines and need to be adjusted to suit. To see if it's your exhaust, just loosen the exhaust bolts and see if it reves up then.

[@plugtheheliflyer]

I'll give it ago and let you know thanks

[@bstill7499]

Awesome!

[@Denver1cycling]

[@Armageddon-qo4wy]

@@TepcoCycleRepair is there's way to clean the muffler? Or do I need to get a new one. Thanks

[@TepcoCycleRepair]

@@Armageddon-qo4wy Yes it's carbon build up. Most have a screen that comes out to clean with a clip or screw.

[@GrowYourOwnFun]

Nice 👍🏻 always good to start simple

[@cas2985]

The “spark arrestor” screen was designed to keep bugs out? I would not take any of my equipment to this guy.

[@TepcoCycleRepair]

I would probably watch the entire video..

[@jwrockets]

Mine not only bogs, it leaks fuel, slowly. I'm going to check both ends.

[@Drippy_dripster]

I have a different one that starts and runs great but the second I hit grass it bogs

[@TepcoCycleRepair]

I would adjust the carb, if that doesn't work, rebuild or replace it.

[@justinsmith847]

Could this also affect it not idling ???? My Stihl will run but will not idle and it's only a year old and I e only used it maybe 5 times ?

[@TepcoCycleRepair]

Yes it could, make sure it's not clogged. If it's not, turn your idle screw up an 1/8 of a turn. Other things can cause it but I would start there. I have a Stihl in the shop now, won't idle due to a partial seizure from straight gas.

[@justinsmith847]

Ok thanks I'll definitely check this I appreciate your help

[@deeLX11]

*How did U clean the screen?*

[@TepcoCycleRepair]

Carb clean and a brass brush.

[@danielsbackforty8094]

Great Video

[@rugged1987]

I tried this and still have the same results fire's up sounds great I cut to start trimming and it boggs out to an idle then I have to start feathering the throttle to bring it back then it does it again ... any ideas ?

[@TepcoCycleRepair]

The diaphragm is probably dry not pumping fuel fast enough, I would replace the carb with a factory carb. I don't bother rebuilding any more and cheap carbs are hit and miss.

[@rugged1987]

@@TepcoCycleRepair pulled the carb and disassemble the lower half of the carb where that diaphragm is it looked good diaphragm didn't look to dry or brittle going to just buy a factory replacement tired of fooling with this thing.

[@SaveAmerica-TRUMP2024]

yep im having the same problem on my FS90R. Runs fine then when trimmer get warm the damn thing just keeps bogging down. My muffler screen was clean. Guess i need a carb after all.

[@DillyDogSays]

Yea 900 videos of cleaning the screens and dam thing still doesnt crank or run or idle.

[@TepcoCycleRepair]

If yours doesn't, in this order, I would check compression, make sure the cylinder bolts to the crankcase are tight, check for spark, use a factory carb not a cheap copy. Clean air filter and exhaust. If it doesn't run after that, throw it in the garbage, probably has bad crank seals.

[@braxtonhill6281]

After I run mine for about 20 min it wants to keep turning off and won't stay running. Have to feather the trigger to use it. Any thoughts? Stihl synthetic oil.

[@TepcoCycleRepair]

Check out this video, this might be your issue. kzbin.info/www/bejne/pH68gn9nnLiafas

[@marttrev4279]

mine does that but its not the screen. Any ideas??

[@TepcoCycleRepair]

Yes, if the screen is clear and removing the exhaust doesn't make a difference, the diaphragm in the carb is most likely dry and not pumping enough fuel.

[@anoldladi]

It would have helped to bring the camera around to show what you did. Otherwise, its just a magic trick.

[@TepcoCycleRepair]

I just loosened the 2 exhaust bolts and pushed the exhaust away from the cylinder. Quick trouble shooting is like magic so I'll take the compliment! 😊

[@SaveAmerica-TRUMP2024]

I checked the screen on my FS90R, it was clean as a whistle. So thats not the issue. Trimmer runs fine then when it gets warm the damn thing just keeps bogging down. Guess i need a carb after all.

[@TepcoCycleRepair]

Check your coil for a strong spark when it warms up.

[@codyandbarbarakillingswort5546]

How do you do that? My trimmer will run for a few minutes then it bogs and surges at full throttle not even enough to turn the head. Thank you in advance.​@@TepcoCycleRepair

[@TepcoCycleRepair]

@@codyandbarbarakillingswort5546 I use an inline spark tester. Check out this video. kzbin.info/www/bejne/pH68gn9nnLiafas

[@ShamanColaLive]

I thought the screen was a spark arrestor. In California all you need is one tiny spark and every thing goes up in flames.

[@TepcoCycleRepair]

It is a spark arrestor, as well as a screen to stop debris from entering the combustion chamber and/or crank while it's off. Remember on a 2 stroke, with the piston at tdc, the exhaust is a straight shot to the crank.

[@817mario]

I have a FS91R clean spark arrester and still bogs sometimes ? Any ideas

[@TepcoCycleRepair]

Most likely the diaphragm in the carb. Try a rebuild kit or better yet a new factory carb.

[@817mario]

@@TepcoCycleRepair okay thanks I will I also haven’t done a tune up. Like replace spark plug and stuff.

[@cdawson615]

Same here but mind only starts bogging down after it get hot and ran for 20 mimuted or more i can get up to half throttle for a sec or 2 and it bogs down and if i let it return to idle it shuts off. Only does this when hot, clean spark arrestor and made no difference.

[@TepcoCycleRepair]

Make sure you have spark when it does that, I have another video of that same issue.

Where I'm from it's to keep the mud daubers from building a nest and clogging it up!

[@Dogpoundpony]

But what if that’s not the problem still has the same problems

[@TepcoCycleRepair]

If that doesn't fix it I would look at the carb. If the diaphragm dries out or gets distorted it won't pump enough fuel and will bogg. That's where I would look next.

[@garyalensr]

The spark arrestor screen is absolutely not to keep things from getting in, its to keep sparks from coming out!! Hence the name spark arrestor.

You are absolutely correct but sometimes things do unexpected second tasks, like keep mud daubers out in the south..
