I was having low power from my saw as I tried to figure out what was wrong. My saw is the same model as this one. I spent the day cleaning the carburetor and not cutting wood. I saw your video and checked the screen on the exhaust and found it to be plugged just like the one you showed in video. At first soap and water, that didn't work, tried alcohol, didn't work. I used Lucus injector cleaner, it worked well. Thanks for sharing the tip, it saved downtime and didn't need to take it in for repair at shop.
Of all the videos I have watched on chainsaw tuneups not a single one of them has mentioned this filter on the exhaust. Thank you for getting this information out there.
My MS170 was only two years old and started bogging down at higher speed settings. Didn't think your fix would apply to such a new saw but it was the solution! Thanks for the great video!
Great tip! I was ready to junk mine over this little issue. Went over everything and couldn't find the problem until I watched this video. Thanks for the help! Runs great again.
This is fantastic advice! I have the same model chainsaw and after I cleaned the screen and the deflector, it ran like a charm. Thank you for this valuable knowledge.
Thank you !!!! This video did the trick for my Husqvarna 51L. Took off the muffler, cleaned it and the screen and it runs like a champ! Thank you again!
Instant results on my Stihl MS 180! I had changed the fuel filter, air filter, mixed fresh fuel, installed a new spark plug and then stripped and cleaned the carb but to no avail. Checked the spark arrestor screen after watching your video and found it to be plugged solid, just as in your video. Cleaned up the screen with some carb cleaner and now the saw runs like a charm. Certainly appreciate you sharing this tip for trouble shooting. Cheers.
Straight to the point! Well done, no music you didn't introduce us to your dog or your kids, though I am sure they are great but I just wanted to know how to tune my saw up and that's exactly what I got.
Over revving a cold saw especially without a bar and chain installed can cause a "cold seizure"as the piston will expand faster at the exhaust port.Always allow the saw to warm up first.
Great video - Thanks for your help. I have a Makita DCS520 that kept bogging. Was skeptical at first as I am in New Zealand and didn't think I would have the screen. Sure enough it was clogged up. Pulled it out fired it up and ran like a dream. Very thankful for everyone taking the time to post videos like yours to help others.
Hey good job on finding the problem! Carb, ignition, and plugged fire screen all yield the same issues with these engines. I'm a mechanic on saws as well and carb or plugged fire screens are the most common problem. And the plugged fire screen is normally caused from the customer not running the saw full throttle, or like you mentioned running to much pre-mix. Have fun!
Gonna check my exhaust next. Rebuilt a Walbro carb on a $5 yardsale Mac 3200 today. Got it started (amd smiled) and seems to run real well (till ya try to start cutting wood). Bogs bad. Step 2... Learn proper jet settings. Step 3... Maybe go back and adjust the needle valve lever thingy properly. I think it may be a little off still. Walbro 247 = .65 - .70. But first... exhaust. Finger crosses and the wood is ready.
Thank you ! I'm a handyman guy and occasionally I've done some backyard mechanic stuff for over a half century. I've worked on all kinds of motors, but never had I come across a motor that uses some little screen over the exhaust. I had looked all over the internet to try to figure out why my small chainsaw was bogging down. Who would think there would be a little screen completely clogged with carbon. I cleaned it off and it's running great now, especially because I put a new spark plug in it. It's just a little Stihl ms150c that I use for cutting branches. Using my larger Stihl for that wears me out. Thanks again.
The screen is a spark arrestor...a dumb thing the government requires....I use my little saw much more than my big one....getting old that big saw hurts my back...I got a little Stihl 194...its tiny, but easy on the back
It’s also good to keep in mind never to run the saw too long or at all without that bar and chain on and tensioned properly. Not only could you over heat and over rev the engine but it can cause very expensive irreparable damage in the long run. Cheers!!
Speaking of the bar - flip the bar over everytime the chain gets removed. Helps keep the wearing of it distributed to both sides. When re-attaching the bar, put a slight upward pressure on the bottom of the tip of the bar while tightening the it.
What ‘very expensive irreparable damage’ would it cause? Why do you think the engine would overheat? You also can’t over rev the engine, short of just holding it wide open for a long time. Chainsaws are designed to rev, and newer ones all have limiters in the ignition. It’s a 2 stroke engine, not 4 stroke.
Great Video. Since its Spring, I went to check on my chainsaws. 2 out of 3 are having trouble staying running. Fresh gas and oil mix. Fresh spark plugs. Now, thanks to this video, I'll be looking at that mesh screen. And periodically clean it after x amount of uses.
Nice,got them work immediately. I have Stihl 170 and 290, both of them had no power and hard to keep them running idle. I opened the front screens , both of them clogged. I did not have new screens and they are hard to clean, so I just got rid of them, when I get new, I put them on.
Great advice. My Stihl MS193T chainsaw would run great at idle, but bog down when trying to rev. I cleaned the screen on the exhaust and the problem is fixed! Thank You!
Thank you very much! Was cutting with my husky and it didn't want to cut it was bogging. Did everything even considered buying tool to adjust L and H settings. Then I found your video and first thing I did was took this wire mesh off and cleaned it. Now its going like a beast and no problems.. Very helpful! Thank you. You get a like from me :)
@Foxboss9 thankyou very much ! You just saved me a lot of money and 2 days sending my chainsaw to a service company. I guess you do learn something new everyday! Thankyou again.
My Stihl MS 290 started bogging down when giving it gas & with no load (not cutting). I tried all the basic stuff,.. fuel, carb setting, air filter, spark plug,... nothing. I pulled the muffler filter and it was basically 100% clogged. I cleaned with carb cleaner and a wire brush, put it back in.... & the saw runs like it was new. I would have never thought of this simple fix if I did not watch this video. Thanks!
Great advice on something I never thought to check. I have a similar model mine is the MS 250 and it is starting to bog a little occasionally so I'm going to check to see if mine has this screen as well. Thank you
I had similar problem with my leaf blower (also a Stihl in my case). It started but ran roughly and had low power. Such an easy thing to check and fix - it simply unscrews. Cleaned by soaking in gas and gentle fine wire brush. Now a part of my annual clean/maintenance.
Your tips headed me in the right direction for a bad bog problem. Had some gas in the saw that was ??? despite having a date on it with stabil fuel additive in it. Replaced the fuel with fresh fuel and it eliminated the bog completely.
Great video. Have the same saw it bogs down when I full throttle sometimes. If you do another it would be nice to see and hear how it fails before fixing.
Thank you... Just went through the carb, New cleaner, spark plug.. Still holding an idle, but bogging and both low/high adjustments doing nothing. Never would've thought to check the exhaust, she's happy now.
Just typed in stihl chainsaw loosing power and this came up. Funny enough I have the exact same saw. Watched the video and that was my problem. 10 min later I'm up and running again so thank you.
My ms170 was bogging down. I was afraid it was a carb or compression problem. Searched the TH-cam and watched this video to diagnose. Turns out the spark arrester was filthy. I didnt even know chainsaws had spark arrestors until I watched this video. Cleaned it and it runs like a top now. Thanks!
Good information.... also remember to check the fuel line in the gas tank. If regular gas is used, then it might have ethanol and that breaks down the rubber in the gas line over time.(94 contains no ethanol.)Then at high demand, full throttle, the line can collapse inside the tank and the saw bogs. Easy fix by simply replacing the line with new one. (I had to wait to have my new gas line delivered so in the meantime I used a steel spring from a pen as a stent in the line and it worked perfectly.) Stihl is a great little saw.
Great tip! I always go a tad heavier on oil. Only because very seldom does the saw idle more than 45 seconds. Other than warm up. It. Its wide open. I'm not a climber. Can understand that. From what I understand they have leaned everything out too. For epa junk. Spark arrestors a good idea. Never a fan of Sthil . Started with Mchulloch only because only descent service guy. 1010,610, and 710. All by age 16. East coast. Prefer Husky or jonsered. Lighter faster. Got a husky 40 brothers I bought my dad decades ago. Dad and one brother gone. Saw still here. 372xp. Saw does the work. Have to be on your toes. .what's your choice and why?
contacted stihl about the arrestor screen for a Stihl 171 and had a reply back The MS 171 supplied in the UK does not have an arrester screen as they were only available in the product version MS171-Z which were supplied in Australia, USA and Canada.
It's a "spark arrestor". I cut logs for 22 years and they tend to clog up on you. It was something that you can do without. The reason we had it was because the worker's insurance demanded we have it . They would check it randomly . But if you take care not to cut wood with the muffler too close , you can just take it off. It is meant to prevent sparks from the muffler to which to this day I have never seen happen.
I thought the spark arrestor was to prevent forest fires, not to appeal to some arbitrary insurance issue. There's a reason the insurer wants it there, for liability. Just because one person never started a forest fire, doesn't mean it can't happen.
I needed this video about 4 years ago.. lol.. I bought a Remington back in 2013 used it for wood cutting, then skipped a year, using just my electric heat.. 2015, I got the Remington out and it wouldn't start very well, finally got it to start then by holding the choke open a little it would idle but if I tried to throttle it. It would die. I just went out and bought a Kobalt 80volt electric. No more gas/oil mix or yanking on ropes.. Anyway good video.. BTW, I sold that other saw for $1.. The guy later said that he couldn't get it to run either.. If I see him, I'll pass this info on to him to check this.. or I might try to buy it back for 50 cents.. lol (he was my cousin or it wouldn't have been $1)
Thank you so much for sharing this. I’ve pretty much done everything EXCEPT check the exhaust. I bet anything that’s the problem. Only been an operator for two years so I’m still wet behind the ears when it comes to this tormenting wretch. But I’m going out there now and fix it... thanks to YOUR HELP. Stay warm!!! I know I can now!!!
I was also having the issue of short idle and no rev. My saw has less than 2 hours of use. I checked everything like has been mentioned on several youtube videos and forums and all was fine, as it should be. It appears the in tank fuel filter keeps the tube off the bottom of the tank too high. I still had, what I thought was, plenty of fuel (about 1/4 to 1/3 full) but was having the run issues. I topped the tank back off and after it idled long enough to purge any air, it ran as it should. Hopes this helps.
Perfect. Too bad I didn't look under the muffler before trying to adjust the carb. I suspect I was heavy on the oil in the gas. Glad to have my little saw back.
Foxboss9 is right about fuel. Not only should it be keept fresh, but at the right ratio. I had problems with my 42cc Poulan saw bogging after running wide open for 20-30 sec. I fashioned a tool to adjust the carb (I'm pretty expert at tuning). It ran much stronger, but still bogged after running wide open for 20-30 sec. I made a batch of fresh fuel at 35:1, though the engine calls for 40:1. That did the trick. It now smokes a bit (no smoke is not healthy), runs super strong, and never bogs. Man, that saw cuts like it's angry now. When you have 3 or 4 2 stroke tools calling for 30:1 through 50:1, you have to be careful. Label your fuel cans!
I had another cause of bogging out that I’ve fixed. I accidently used chain oil in the fuel instead of T2 engine oil. The engine run at idle but bogged out at high revs. When I put the right fuel in it was OK. I went through all of the cleaning and adjusting processes it was only when I tried a new mix of fuel that I realised the fuel in the tank was yellow, the only T2 oil that I have is pink but both bottles are black and look the same. All the best . . . Andy

Cole B yu spent the day cleaning a carb.. don't quit yur day job
Next time try to use carb cleaner and it should be OK
How to start a chain saw?
"big ass puss" People like you dont quit their day Or night jobs.. They get fired!
next time it clogs up chuck it in the trash that’s where they belong.
Of all the videos I have watched on chainsaw tuneups not a single one of them has mentioned this filter on the exhaust. Thank you for getting this information out there.
My MS170 was only two years old and started bogging down at higher speed settings. Didn't think your fix would apply to such a new saw but it was the solution! Thanks for the great video!
The mesh screen is a "Spark Arrest" preventing sparks from flying out the exhaust in a dry environment ;)
Great tip! I was ready to junk mine over this little issue. Went over everything and couldn't find the problem until I watched this video. Thanks for the help! Runs great again.
This is fantastic advice! I have the same model chainsaw and after I cleaned the screen and the deflector, it ran like a charm. Thank you for this valuable knowledge.
Thank you !!!! This video did the trick for my Husqvarna 51L. Took off the muffler, cleaned it and the screen and it runs like a champ! Thank you again!
I had crap old fuel. As an amateur I never had realised this could have such a profound effect. New fuel, works a dream, thank you!

If you're spark arrestor is clogged like that, your mix is too oily, and exhaust port needs cleaning 🧐
Thanks for the really helpful video.

It. Its wide open. I'm not a climber. Can understand that.
From what I understand they have leaned everything out too. For epa junk.

Antonio Arellano run full synthetic mix oil it wont plug up. run the cheap stuff it will plug up because it has crude oil in it
i would think if it was throwing sparks it would be a good sigh of the saws engine starting to die.
The sparks are carbon, not metal.
Good info! Thanks for your input. Experience will always win.
I thought the spark arrestor was to prevent forest fires, not to appeal to some arbitrary insurance issue. There's a reason the insurer wants it there, for liability. Just because one person never started a forest fire, doesn't mean it can't happen.

Thankyou. Similar problem on strimmer. Didnt know there was a gauze on muffler. Sorted my liw power, it is like a new one now. 👍

Perfect. Too bad I didn't look under the muffler before trying to adjust the carb. I suspect I was heavy on the oil in the gas. Glad to have my little saw back.
Foxboss9 is right about fuel. Not only should it be keept fresh, but at the right ratio.
I had problems with my 42cc Poulan saw bogging after running wide open for 20-30 sec. I fashioned a tool to adjust the carb (I'm pretty expert at tuning). It ran much stronger, but still bogged after running wide open for 20-30 sec. I made a batch of fresh fuel at 35:1, though the engine calls for 40:1. That did the trick. It now smokes a bit (no smoke is not healthy), runs super strong, and never bogs. Man, that saw cuts like it's angry now.
When you have 3 or 4 2 stroke tools calling for 30:1 through 50:1, you have to be careful. Label your fuel cans!
FANTASTIC VIDEO!!! Thank you!!!

Great info... Dad always said it's the big three -air, fuel and spark ... Most fail to realize breathing = inhale AND exhale.
Amsoil synthetic two stroke oil at 100/1 mix ratio and high test fuel is your best way to go on these saws ! Never had a screen clog problem!
thanks, this got me up and running!
Christopher Andrews AWESOME.. Now for the real work..
I had another cause of bogging out that I’ve fixed. I accidently
used chain oil in the fuel instead of T2 engine oil. The engine run at idle but
bogged out at high revs. When I put the right fuel in it was OK. I went through
all of the cleaning and adjusting processes it was only when I tried a new mix
of fuel that I realised the fuel in the tank was yellow, the only T2 oil that I
have is pink but both bottles are black and look the same. All the best . . . Andy

Might also check the impulse line for cracks. Replace it if cracked or it won't idle/spool up right.
