Thank you so much. My husband passed away 6 months ago and I've been learning how to operate all his yard equipment. It's been tough but with fantastic videos like yours, I've been successful (so far!) in getting his riding lawn mower, the blower and now the weedeater up and running. I followed your instructions and now my weedeater is running like a top. Wow. You're a life saver!

My 14 yo son just watched your video, and fixed our weed eater following the instructions you provided. Thank you! My husband is happy not to have to take it in for repair.

Thank You!! This has been bugging us for about a week. We could not figure it out until we say your video. I am so glad. Have a good day.

Your video saved me from taking my Stihl FS240R line trimmer. It was bogging down about an hour into running just fine. The screen was totally plugged as you had shown. I couldn't find my torch and tried laqure thinner that couldn't cut to clean it. Looked a little harder and found my torch. Burned it all clean, put it back together and ran great. And was able to finish the job. Thanks so much bud!!

My stihl was running like shit and i didnt know what was bogging it down. This fixed it immediately great video.

I do not know about anyone else,but I never knew that was there. Excellent video bro!!

People like you who show people like me, free of charge, how to save a ton of money are Angels. Thanks so much!!!!

This nailed it for me. 15 minutes and it started up fine and runs at full power again. Thank you for a great video!

I had mine loaded up and ready to take it to the repair shop, got out of the truck, went inside and Googled to come across your video. Back out to my shop and fixed it. Runs like a champ now. Thanks! Great vid!

Thanks for the video. After cleaning the carb and spark plug I was stuck, the trimmer still bogged down. Your 5 minute video did the trick and about 5 minutes later the trimmer was running like a champ!

I tried your solution and it worked perfectly!! My Stihl trimmer suddenly became very sluggish and lost power. I followed your directions, but didn’t have a propane torch available and wound up soaking the screen in carburetor/choke cleaner and scrubbing with copper tubing brush. After reassembling the trimmer it ran like it was brand new! Thanks for the help. This has been one of the best tips I’ve found on KZfaq.

My Stihl trimmer was working fine one week ago, and today would die the instant throttle was applied. It did not have the exact screen setup as this video, but after locating the screen, sure enough, that fixed it. Thanks for the video, saved my trimmer.

Hi! Just wanted to thank you for the information. I have a stihl fs45 that I purchased at a yard sale years ago and could not get it running. I finally broke down and bought a replacement carburetor. I was able to get it running but it bogged a full throttle. I stumbled across this video and proceeded to check the spark arrester. It was near clogged, so I decided to remove it. My model has a bolt in type with a mesh tubular screen attached. I reinstalled the bolt in tip, ran it, and adjusted the carb. It now runs as good as new! Again, thank you!

My old Stihl FS38 trimmer had no power. Was thinking of ditching it and purchasing a new one. After watching your video mine now runs like a dream. I didn't have a gas torch at my disposal so just used a wire brush and a pair of pliers to hold it. You saved me $180 the price of a new trimmer. The least I can do is subscribe. Thank you.

I had this same issue with my 5 year old fs70r. A tune up kit didn't help. The dealer couldn't get to it for 2 weeks... I saw this video & BAM!!! Problem solved! Thank you

The eyes, the eyes... I thought I was being sucked into a blue abyss, and then the motor started crashing me back to reality. Hahaha... lovely ambience with kids in the background. Takes me back. Well off to the workshop to fix a friend's brushcutter with exactly the same problem. I said to her as she handed me her machine, " Bet you it's a wasp nest in the exhaust pipe or a grubby air filter." Well it might also be the clutch or cable, but I dont think so. Excellent video.

Planned on taking the Trimmer to the repair shop but found your video and it solved my issues. The STIHL trimmer runs like new again. Thank you for the video.

My wire mesh was a little different than yours but in the same place. Followed your advise and it was working like new. You saved me 175.00 as i was about to get a new trimmer. Thank you TY!!!!

.... I have been messing with my Stihl FS 55R weed trimmer for days now. It would barely idle. The last time I had it it ran okay. Thought it was the gas/oil mix way to rich. No. .... I cleaned the carb. Didn't find anything really dirty and it still would idle very rough it ran at all. .... Found this video and the light bulb in my head went off, THAT'S GOT TO BE IT!!!! I am mechanically inclined and what this video showed made perfect sense. The exhaust could not, "exhaust". .... Mine was a little different than in this video but figured out how to get it out. You guessed it, totally clogged. Heated it up, wire brushed it off, blew it out with air, reinstalled and it ran like new. .... THANKS SO MUCH!!!! ..... Trimmed everything last night.

I am a senior female and your video was just what I needed to get my Stihl weedeater running great. It was fast and easy and you saved me some money since I didn't have to take it to the dealer. I think anyone could follow your instructions. Thanks so much.

Thanks man, was about to throw in the towel after several hours of removing, inspecting and cleaning with no luck. Your short video sent me running back to my FS 250R where in 10 minutes the thing was running like when I bought it brand new 13 years ago!!

OMG thank you so much man, I've been having this exact problem and was about to take it to get repaired when I thought I'd try your method instead and it worked beautifully.

Awesome, this solved the issue I've been having with one of the Stihl's at work for years. Did a full teardown twice, but didn't even consider the spark arrestor as a source for the problem. Big thanks from southern Quebec!

You're the man! This video saved me from spending $200+ on a new trimmer.

Is the third time for me to try to make a comment and I'll blame my phone in me I just don't get along with these electronics and I ain't complaining LOL. Your video was very informative and I appreciate you showing how it ran because I knew exactly I was watching The Right video when you showed that 10 minutes later reminds running like a champ I just got to get the adjustments on the carburetor right cuz I was fooling around with all that also. Thank you again and I hope this comment doesn't disappear like the last two.

You are the MAN! My pop is a veteran lawn care professional; like... an o.g. of John Deere. HOWEVER, while his final determination was that the carb HAD to be changed, you blew that evaluation out of the water. I followed the process you described in the video, and my trimmer is LIKE NEW! Seriously, thanks guy!

Thanks mate from Australia. You just saved me buying a new cutter after cleaning everything I could expect that. Legend and good luck to you. Works like new now thank you!

Had low power on my unit, this was the first video I watched and it worked perfectly. Thanks for posting this,.

Thanks for the video. I searched for “bog” not knowing if it was a real word. Still don’t know if it is, but my string trimmer is operating again!!

Mine wasn't nearly as bad as yours, but it was definitely bogging down. It took me about 5 minutes to do it and back to full power. Thank you so much for explaining it so well.

Can't believe it was that easy my coworker just gave me one of these and that's exactly what it's doing

Same as Pat McCarty… it worked perfectly. 10 minutes to fix. Thanks so much!

Thanks so much. A regular charcoal lighter holding the screen with needle nose pliers takes a little longer but worked the same. My Stihl weed eater is once again bad ass! Thanks again.

Thanks, you saves me alot of headaches by making this video.

I want to thank you for the the heads up on that. It worked perfect and you were right 10 to 15 minutes and it was running like a new one. Awesome thanks again. You saved me some money because I was heading to the Stihl dealer to get it fixed.

Brother you just saved me from a major meltdown l. Yard implement bad day to the highest level. Ever in the the niagara region of Ontario I owe a few cold bevies! Thanks so much 👊🏻

My Stihl was doing the same dad-gum thing. Works like a champ now, thanks for saving me money!

Man I have F'd with mine longer than I want to write about. I cleaned carb (more than once), new plug, etc... Still same issue. Took to small engine repair shop, and it still ran like crap when I got it back. Then I put a new carb and lines, ,,,same issue. Then I googled it, your video was the first I watched. Unbolted the exhaust screen and cleaned it and now it finally runs. Thanks for the video. I should have looked this up before. Fixed in under 5 minutes

Thank you! Exactly my issue. Saved me so much money time and STRESS! Got a full day of mows booked first thing tomorrow. Needed this.

This saved me a trip to the stihl shop thanks for posting

SIR!!!! YOU ARE THE MAN, tried carb adjust/cleaning air filter plug......people prob losing a lot of money on this thanks a ton I owe you a beer

This is why I love KZfaq. Thanks!

I love the happy children playing in the background it reminds me of my shop. When ever I go to work on something my children always want to help. I love it when we bond over hard work. Not only does it build our relationships it teaches them how to take care of their equipment. Great video! My Sthil FS55R will start but when you give it gas it bogs down and shuts off. I hope this fixes it.

Worked like a charm! And I love the kid chaos in the background! That’s real life bro! 😂

I was ready to buy a new one, five minutes FIXED!!!!! Thank you so much!!!!!!

Thank you so much for posting this video. Cleaned it and weedeater worked like a charm. I really appreciate your help.

Saved me having to put hedge trimmers in the shop, thanks!

I was all ready to buy a tune up kit... and bang there you were.... awesome vid thankyou very much. Someone needs to send you a cape.

Like everyone else said, thank you, this fixed my issue. Great video.

Thanks for the video,after changing the plug, taking the carb off and cleaning it I decided to watch the video. Now it's running like a new one again

F**king AWESOME! I didn't have a torch... I used a bic and scraped the stuff off with the screwdriver... Thanks bro! Saved me money and time wasted dropping it off to a small repair shop... Much appreciated!!!

Good stuff man. I just did this based on your video and my trimmer is good as new! Thanks for the info!

Well done. My Stihl, FS45 had a slight variation of the metal mesh screen but same principle. Worked like champ, trimmer is running like new again at all throttle settings. So glad I checked your video before messing with the carb adjustments. Thanks.

My Stihl FS66 ran funny one day but I got it to work. The next day it wouldn't run, like this video. No problems for 38 years. I rebuilt the carb, new spark plug, new base cylinder gasket, new carb gaskets and changed fuel. But nothing worked until I tried cleaning the muffler screen like in this video. Bam ! Runs like it always did, I 'm shocked.

So the advice in this video is spot on apart from one thing. I have a 4 year old FS 38 sthil whipper snipper and it does not have the mesh screen. There is, however a exhaust port attached to muffler by a 16mm nut. I undid this nut and out it popped with a cylindrical mesh top. So I did as shown the this video and burnt the mesh on my butane stove. It cleaned up a treat and now whipper snipper works like new. Thx bud for a great tip n video

Thank you for making this video!! I was able to fix my Stihl FS 56 RC by myself!!

Thanks, you nailed the issue, 10 minute fix! Gumout Carb/Choke cleaner works great on the screen btw.

Thanks man you just saved me a couple hundred bucks when everything and everyone told me it was a bad carb I tried your fix thinking it was a long shot and it’s like brand new You Da Man!😉

Thanks man!!! I am sure that is my problem. Never even really knew what a spark arrested was until today.

Great job! Now I'm going to clean me screen. Good camera work with the close ups. Very good.

I did this and worked perfectly thank you for saving a trip to the stihl shop.

Stihl FS 56 RC - this took 10 min and was perfect! Thanks, man!

Super easy. Knowledge is power. Thanks

Just fixed mine using your video! Only had a steel brush and carb cleaner but did the trick. Thank You!

Thanks for the tip dude!! The hardest thing about it was finding a T27 screwdriver. Once the screen was burnt off and spark plug cleaned, my FS 56RC started right up and sounded new again!

Fixed my problem and saved a trip to the repair shop. Thanks!

Thank you you saved me a trip to the repair shop

Thanks so much for the info brother! You saved me a lot of time and money. I followed your directions to a tee, and she’s purring like a kitten!!! Thanks again man!

Holy Toledo!!! What an excellent video dude!!! Thanks for sharing!!!

This was a great tip. Trimmer fired up on first pull and ran like a champ. Thanks. One small deviation. I used my air compressor to clear the screen. The bulk of the carbon blew right out.

Saves 200 bucks thank you different model but worked like a charm

It's a very common issue with the Stihl leaf blowers that I was working on for where my dad used to work & my auntie still does,at a nursing home.

Absolutely a life saver, love KZfaq and folks like you. Not all heroes wear capes 😉 10 minutes and I was up and running again! Also, I used engine degreaser & a tooth brush then a good rinse with water. In case anyone might want to try that way. Fires up & runs like new! Thanks so much sir, appreciate not having to take it anywhere or buy parts that aren't even needed 💙

Great video you just saved me hours - cheers. I didn’t have a blow torch so I cleaned mine with a wire brush. This was a bit slower but worked.

Gardner, you are my Hero. You showed us how yours was dong and mine is identical. Bogs down when you give it gas. I fixed the spark arrester just like you said and Bingo, Runs like New. Many thanks you you Sir. You got to the point & I appreciate that. WallsBeeMan on your tube

Thanks a bunch for this! I never realized there was a screen there. Runs like a top now!

I have fs 35 and my spark arrestor screws into the muffler. Clogged right up cleaned it out now and runs like a champ 👍

Thank you so very much for this simple fix, my trimmer is like turbo charged now!

It work about 90% mine had a round screen with a nut that held it in. But after burning off the carbon build up it like a new machine .... THANKYOU for posting this!!!!

Tried it with my stihl and it works perfectly again. Thanks for the video!

10 min later, fixed. Thank-you.

Damn the stuff you learn off you tube.you. guys that make these videos have no idea howe much money yall save us .Had i'd not seen this i'd never known and someone that could had worked on it would had charged me for something entirely different. You guys make a Big difference in us d.i.y. owners.I really appreciate the Heads UP..

Awesome !! Just did this and it worked like a charm ! Happy belated Father's Day !!

Thanks I had replaced all filters carburetor and fuel line never thought of the spark arrestor running great

Thanks for this video. I am now going to make this part of regular maintenance.

It worked! My FS70R runs like new. Thanks for the tip!

Thanks! My Stihl weed whacker came alive after cleaning the spark arrestor. Hasn't run like this in a long time.

Great tip! It worked perfectly. Just the fix I needed.

Thank you for the video. Fixed my problem exactly.

Great video thanks. I did not know about this. Will try it tomorrow after I get off of work. Mine has the same issue as yours did.

Thank you! This saved me a lot of money! Seriously thank you it worked like a charm.
