I have the same type, my spark arrestor is completely gone but still bogs down?

@machinesnmetal Thanks

Check your exhaust port to be sure it isn't closed up with carbon deposits.
what about brake cleaner?
Jim McConvilleМісяць тому
@machinesnmetal the mechanic in me thinks pressurized brake clean will clean anything
Can you completely remove the spark arrestee as well? Or will it not run without it in there?
machinesnmetal Місяць тому
You can but then you won't be arresting the spark and that could be a safety issue depending on how dry it is where you live
Try running "Red Armour" 2 cycle mix through it, it will clean it out and keep it clean as long as you don't over mix.

Shindaiwa Red Armour in my opinion is the best 2 cycle mix on the market.
I have been soaking mine in combustion chamber for a week and it looks the same. Gonna try this! Thanks! FYI my machine is 11 years old and always had the right mix of stihl/Castrol oil. I think part throttle makes it happen faster, as my blower spark arrestor is still really clean.
Exactly the problem! Thank you!
Perfect! Worked like a charm!
Is their anyway to clean the screen if you don't have a torch.

Not in my experience, you could order a new screen from your Stihl shop. Get a couple-
Just had same issue on fs45 but now I can't get an smooth idle it surges up and down while idle but runs great while not idling what would cause that?
third video showing that it is the spark arrester *(sometimes spark arrestor)*
Very "to the point" presentation. I wish everyone did it this well. 👍
Wow amazing and informative! Thanks

This happened to me twice in less than three seasons, on the same trimmer. I will not be using Echo fuel or oil on my 2-stroke motors anymore. My neighbor has never had this happen on his and all he uses is Stihl Oil.

Ive only ever used shindaiwa red armour 2 stroke oil mix. Along with chevron 94octane fuel I can't say I've ever had a fouling problem in the past 10 years.
My Stihl runs great for the first 20 minutes then it's just bogs down and won't rev after it warms up!
Do we really need that creen there or we can simply remove it?

Only speaking from what I know I remember back in the day we used to have a similar device in the end of our dirt bike tail pipes so that when you were riding in a dry forest in the summertime you did not shoot out some Sparks and set the forest on fire it's called a spark arrestor I do believe they used to check dirt bikes on the trails to see if people had removed the spark arrestors as it would raise the chances of a forest fire. So in my mind the spark arrestor in a trimmer is there mostly for the same purpose.

@machinesnmetal That's an excuse they use to fool people. Meanwhile they make tons of money at repair shops and selling new ones to none smart users. First of all try setting grass in fire yourself using one . It's possible but not absolutely easy. Thank God I knew about this screen. Now my blower works properly.
machinesnmetal 8 місяців тому
It's primary function is to catch sparks coming out of the muffler and setting dry grass on fire. I would leave it in and service it as required
Great video. Just a tip with the flame - pull back a bit, the hottest part is at the tip of the bright blue inner flame. Thanks for sharing!
...and don't light your bench on fire...
Timely advice. I was just about to replace the carburetor after many frustrating attempts to tune my FS55. After this she's purring like a kitten, just like new.

Echo is better more cost efficient and have the same not more power then sthil

I couldn't agree with you more my friend
I just checked mine after 15 years of use, and mine is clean as a whistle, I never let small two stroke engines idle, I start them up and full throttle and switch it of between sections, and Its still going strong
Nicely done. No diversional music or intro. Right to the point.
Thank you ! Bravo!
Something as easy as a spark arrestor screen being clogged causing that much problem making me look like a fool 🙄. I cleaned my km 56 r and fs 45. Brand new machines 😁
Bought a used trimmer - started to think i got ripped! Looks like it was a good deal now!!! Cheers!
If you don't feel comfortable using a torch to clean the screen, use carburetor cleaner

thanks. was hoping for an alternative like this
Your the best help.😎🇨🇦😎🇨🇦
I don't even bother cleaning the screen on mine. I usually just remove the screens on any equipment as soon as I buy it and put the screen in a zip-lock baggy marked with the model and brand of machine it came out of and file the screen away in a small box with all the other screens.
How do you stop over oiling?
I use TrueFuel 50 to 1

Stihl makes a premix, I don't like it, seems to be kind of harsh on the fuel lines/ carburetor disphram
That is music to my 👂👂 now do you have a video.on to work blade engagement on LT 1000 Craftsman'.riding mower I have one .when I go to disengage the blade,s they will not stop
Robert MailhosРік тому
@machinesnmetal it has the manual blade.engament the slot is shaped like a upside down J the problem is there is too much slack when I go to engage it
machinesnmetal Рік тому +1
Does it have an electric PTO clutch or the manual swing style lever to engage?
Or I just take them off. Lol
Thank you, thank you, thank you! I was getting ready to buy a new FS56, but you just saved me $220! Awesome video!
I have this same model. The FS 55 RC - except on mine, it doesn't end and fire out the back like that, it turns sharply into another metal box marked 'KAT'.
There's no way of opening it that I can see.
Any idea why? I was wanting to clean it out as you did.
Bread SandwichРік тому
@machinesnmetal I'm not sure it would be much of a video :D
I've been told they made a version that used a cat.
No wonder it gets so damned hot.
Very nice and usable video. I had same problem and I resoved it because of advice from this video. Thanks for this.
This is a very helpful video. I am having trouble getting the old spark arrestor to fit back in the slot after cleaning. Any suggestions? Thanks. Kent
machinesnmetal Рік тому
gotta kinda reshape it to fit, or just pick up a new one, they are dirt cheap.
That gas is fine. You can't guess the ratio by color
Mine is still bogging down. I did what you did in the video and tried adjusting the carburetor. It still bogs down and shuts off. Any idea what to try next?

Have you tried cleaning your carb or putting a kit in? If you're mechanically savvy replace the fuel filter and the diaphragm in the carb and that should fix your issue. I'd bet my bottom dollar it's carb related. I've replaced hundreds of carbs on those due to failing pressure tests.
They're not expensive to replace (carb) and often if there's a piece of dirt in the check valve or somewhere even a sonic clean won't bring it around. Might be able to get away with a new diaphragm.
Check your local dealer or get the numbers off your carb and bring them to a shop and they can get you a carb kit/carb. Well worth the money as the FS55 is a great rig for the average home owner.
90% of the time it's a plugged exhaust screen we see. But there's a fair few replaced carbs too.
Thanks. Worked great.
Very helpful! Thanks for taking the time to share it..
I don't have a torch , but I just put mine in a little cup
Of gas , let it sit a min swish it around , wipe it clean ?
machinesnmetal Рік тому
Ive never tried with gas before, always used a torch.
what if you dont have compressed air?
Alex_1210Рік тому
Use a tooth brush with some soap
machinesnmetal Рік тому
take it to your local power equipment dealer, or neighbors place.

Hi I tried this even removed the mesh still bogging. It only runs without the exhaust mesh plug removed
machinesnmetal Рік тому
Your exhaust port itself might be closed up with carbon, try taking the muffler completely off and look in the port and see if it's closed up like a cave.
Bread SandwichРік тому
While I take no responsibility for your choices, a lot of people run these without the screens on. They're just there to prevent the liability to the manufacturer around the obvious fire hazards of dried grasses, combined with shooting sparks and the like.
If you're aware of it and understand, it's your option as the owner to go naked.
Brian PapeРік тому
Any chance either of you figured this out? I can't get it to
Run with the exhaust on
richard unwin2 роки тому
I have the exact same problem, runs great without exhaust add soon as I put it on it stalls out? Did you figure out what was causing this to happen to ures?
2 different Stihl dealers told me my FS40 needed a carburetor, $50 bucks, i took carb off and cleaned it up and i could not believe any thing wrong with carb, hated the idea of trashing this Stihl Weedeater. as usual i turned to youtube and watched this video, i took one screw out of muffler and the screen was clogged w/carbon, i used a torch and compressed air and weedeater runs like new ! Thank You for saving me $50 and more importantly my Weedeater ! I hope Good Fortune heads your way my American Friend !
Super helpful! Was about to chuck mine in the bin. Did this and wow its like a new trimmer again!
