A massive thanks for this video Charles. My KM 56RC was suffering the same problem, and I just assumed it was the carburetor. So, I bought a replacement, tried fitting it, and nothing changed. I had noticed over the years that the trimmer was slowly performing worse and worse. This simple fix has brought the whole thing back to life again. I was on the verge of just buying another trimmer. Awesome!! This video is the exact reason that RUclips should exist. Greetings, from down under here in Australia!! (Even though it's 6 years later :) )
For the last 18 months I've not let the lawn crew edge or use a weed eater in my back yard. ruclips.net/user/postUgkx_rBCFuDW1zD6blTGhLkvAkxU657uR_lG I didn't like the fact that they just kept cutting the edge of the lawn further and further from the rock lining the flower beds and leaving bare ground. And the grass was trimmed or scalped several feet around trees, etc. It was a constant battle with them so I told them to just mow and no trimming. I have Zoysia grass so it grows pretty slow. Obviously after a while it could use some trimming. I'm in my 80's so I can't do much of it myself.Finally I decided that if I could find a lightweight battery powered trimmer I might be able to do some light trimming. I decided to buy the LST201 20V trimmer. And it works great for my needs. I have back yard with about 150' of flower beds and several trees to be trimmed. I can lightly trim the whole yard with a single charge! The grass I trimmed was only a few inches high but the trimmer was more powerful than I expected.
Thank you! I had the same problem and cleaned the carburetor, air filter and replaced the spark plug with no luck. Watched your video, cleaned the spark arrestor and it runs great again!
I bought new carburetor, fuel filter, spark plug, air filter, I was 10 seconds away from bashing this thing into pieces. And it hit me check out RUclips. Thank you for posting this video. You saved this weedeaters life. It stared and ran great first pull. Thanks again
Thanks for sharing this video. My FS 55R was doing the same thing. I had replaced the spark plug and air filter and still wasn't running right. I saw your video and cleaned the spark arrestor and it runs like new now. I didn't have a torch for cleaning it but used a 2 burner propane camp stove and it worked like a charm. I held the arrestor over the flame with a pair of vise grips. Thanks again for the tip.
Remove the spark arrestor so you no longer have to worry about it. Plus you'll gain a little power and have faster throttle response since there won't be any restriction in the exhaust. I remove the spark arrestor on every equip I own and makes a big difference.
@@seabass22 I've been running various 2 and 4 stroke equipment for over 30 years with no spark arrestor and never has anything ever caught on fire. You'd have to pour gas on something flammable and hold the muffler right on it with the throttle wide open for it to possibly ignite.
Thanks for this video, save my sthil weeder, have the same problem. I used to clean, gasoline and wire brush and is enough, now it works like new, thank you. Please make more videos
Buddy I appreciate your video it took me 3 hours to weed eat quite a bit of grass around the house because of the bogging down in the motor found your video online you save my day thank you appreciate it
Charles Waggle Thank you for taking the time to video and post this. I had the same problem with my 55rc. Your video and narration gave me the courage to take it apart, like you did. In addition to cleaning (with a torch) my clogged spark arrestor, I also removed the 4 screws mounting the 'gas bubble' and found the diaphragm hole clogged. I few gentle pushes and it shot a gas stream like it should. I put it back together and it started on the second pull and has been running like a champ since. You made my day happy! Thank you! Dan Peters
My Craftsman is bogging down at full throttle. I checked the spark arrester, which BTW is stupidly built into the sealed muffler, the screen is in fine condition.
Much obliged for the information. We don't use Pukeanol gas only premium RV gas without it. Got same unit with same condition will clean it just right like shown.
Hey, THANK YOU SOOOO MUCH!!! Your video really explained my problem and I was able to fix it 100%. (It had been bogging down and shaking like a bloody tornado was coming...lol). Thnx. Brian.
If my first video is as good as yours Charles, I'll be a happy camper. You clearly identified the problem, said how to fix it, then showed how to get at the part and put it back on... all one handed. Well played, Sir!
Thank you so much. I have a KM 56 R and I removed the screw but wasn’t sure I was doing it correct and stopped. Found your video and finished the job. That was my problem with my Stihl and my stihl blower. I appreciate you men for making these videos to help us women save money to do these simple fixes. 3 years ago I paid a small engine shop $120 to clean my back pack blower. What a rip off. A 15 minute job and I was really scammed. Bless you for this video and saving me $250 for t
Dude...the first video that actually helped me fix my problem! I liked how you were A) to the point, no endless dribbling on about this or that, B) that you demonstrates what was wrong that you were trying to fix which helped me to know to keep watching and C) that you showed exactly how you resolved it. Only thing I did differently was use water, Comet, and a scrubby sponge to clean mine. Thanks! Saved me a lot of headache!
Hello Charles. I did just as you said and now my old FS 56rc works perfectly. Put simply, this video is the most useful and effective I have seen so far on RUclips. Seriously! Saved me lots of time and money. Well done and many thanks!
I just went out and bought a carburetor for mine today after I took the original apart and cleaned it up. Out back together and still had same problem. So now I think I just wasted money on a new carburetor. Thanks man!!
Yeah i just had to do that with my fs 56 rc. I changed the airfilter, spark plug, an muffler thing. Been a few years so i changed it all. Mine was acting just like that, had no power. My muffler thing was caked up.
In 2 years my motor hasn't had a tune-up no wonder it's bogging down. I going to start cutting yards, so for reliability, I decided to do a tune up. I never thought of a spark arrestor. Oh well, going to get the parts tomorrow.
Looked at mine today but it doesn't have one! It was in the shop. Not sure if they took it out or did it disintegrate? I can't see it making it run like that but maybe. I'll go by there and see. Thanks for the video!
Too much oil or poor quality oil. Use Stihl Ultra or Echo Red Armor and it will not gunk up like this. Also these need to be run full throttle as much as possible or every few minutes.
Do all engines have that net? Mine runs perfectly fine on idle but stalls as soon as I press the throttle, I removed the cover and looked for that thing everywhere but didn't find it.
Thank you for the video, this nailed the issue I had and 5 minutes later I was golden again. By the way, I had read in my owners manual to NOT oil the felt air filter. I looked for it because that's the way I was learned to do it also. Probably won't hurt anything but thought I'd mention it.
I went through the carb. then 2 more times, thought i had something wrong, never did i think about spark resistor being clogged. I try tomorrow because the hammer was going to take a turn if i did not walk away. Thanks good video!
Thank you so much, mines running like a champ again too. Not sure how much $ this saved me from having someone else fix it but I’m sure it was a decent amount.
AWESOME VIDEO!!!! Cleaned and took apart whole carb (did not help) before seeing this video. After... runs like the day I bought it, 10+ years ago. Thank you!!
Well, I'm about to take mine to pieces with renewed confidence. It may or not be the problem, but we will see. One thing you did make me consider was reading the manual. ;-)
Thank you, Charles. I've got to finish up 3 acres that can't be mowed in a California high fire area and both my F56's had this same problem. Might be your 1st video, but it was of tremendous help for me.
It's a spark ARRESTOR screen, not "resistor" as written in your title! BUT - that was EXACTLY my problem! Once I cleaned it, it ran like new (and it's nearly 30 years-old!) THANKS! 👍🏼
Had same issue with mine. Suspected everything else first. Bad gas, clogged fuel filter or air filter. Saw your video and 10 minutes later had unit running awesome again. You 'da MAN!!

You are truly welcome and I’m glad I was able to help…
Thanks! There is nothing like experience, even another man's.
Mr. Bob, you are truly welcome and I’m glad I was able to help you….
Thanks for you video. How do you clean the carbon build-up off of It?
Carb cleaner or burn the carbons off with a propane torch and get it red hot
Yeah with carb cleaner or brake cleaner…
This happened to me just the other day, now going to try this fix. Thanks for the info.
You are truly welcome and I am glad I was able to help…

Big Texas they’re there for I think California and national forests. If you get caught there without a spark arrestor, you can get a fine.
@@seabass22 Screw that, no ones catching me doing anything on my own property.
Big Texas I live near one of the biggest national forests in the country, and lots of people live there. I doubt anyone would ever say anything though
@@seabass22 I've been running various 2 and 4 stroke equipment for over 30 years with no spark arrestor and never has anything ever caught on fire. You'd have to pour gas on something flammable and hold the muffler right on it with the throttle wide open for it to possibly ignite.
Big Texas yeah I know what you mean. It’s the EPA that comes up with this shit.

Much obliged for the information. We don't use Pukeanol gas only premium RV gas without it.
Got same unit with same condition will clean it just right like shown.
Can anyone tell me why this might happen to it? What’s the cause of it clogging?
I believe it has to do with the mixture of oil to gas ratio… and if it is mixed with to much oil to gas it sludges up the screen…
Had the exact same issue this year. Got mine 2 years ago too.
Glad I was able to help you…
OOPS! I meant to say shaking like an EARTHQUAKE... lol lol Brian.
Good video, my trimmer was also doing the same. Will try that fix on mine.

Coach Chris Thank you!!!
Do all engines have that net? Mine runs perfectly fine on idle but stalls as soon as I press the throttle, I removed the cover and looked for that thing everywhere but didn't find it.
Not all trimmers do just the new ones that are emissions…
Dude that fuel mix is far to rich . Look at how blue the smoke from the exhaust is. No wonder it was clogged up.
Yeah I changed that up and switched to synthetic oil…
Thank you for the video, this nailed the issue I had and 5 minutes later I was golden again. By the way, I had read in my owners manual to NOT oil the felt air filter. I looked for it because that's the way I was learned to do it also. Probably won't hurt anything but thought I'd mention it.
