A friend asked me to get his MS171 running properly. It would start ok, but bog and stall as soon as you touched the throttle. This vid helped me sort it out, it now runs brilliantly....thank you for posting.
I was running this saw for about 2 hours at about a 30-50% duty cycle th-cam.com/users/postUgkxfQm1wmg0ItKDLavxj1nXtQY9HP7EF504 and it did a great job. I used the lever for the built in sharpener to clear chip buildup out more than to actually sharpen the chain. It managed to cut some hardwood stumps much larger than it's size without bothering the neighbors with hours of 2 stroke noise.
Thank You so much. Could not get it to idle w/o dying. Now it runs. I might tweek it a little more, but I’m back in business. You just cost my small engine guy some $$. Hehe. Thanks again!
Hey Matt, Appreciate the simple explanation. Saws usually run pretty good. Sometimes they run real good and in the back of my mind I'm thinking 0000 I hope this thing is holding adjustment and not gonna let go on me. I feel better about zeroing then out occasionally and making sure everyone is where they are suppose to be. My Brother snd Dad are not matinance people. It kills me to watch them guys run them saws out of gas. (BTW I'm a dumbass, ask em) I always say "Did ya check the crank case oil when you gassed it up?" Lol tear em up, it'll quit when I got it. Lol Brother: "How many years have we been running saws out of gas." I reply..." about as many years as dad has been buying chain saws"
Is it worth tighting the high mix and lowmix carb screws all the way to start with. Been working with chainsaws for 5 years and still can't get it right. Brilliant video by the way. Keep up the good work.
My MS 280 has the high speed adjustment blocked off. Instead there is an electronic connection to the carb. It is running way too rich on the high end and there is no way for me to lean it out. It's tough cutting logs at 1/2 normal rpm, any suggestions? (ps - it's been to the local dealer, new carb, new plug).
Hopefully this will work 2morrow. My 025 pops, then it poops. Been struggling with it for a year. Still have yet to be able to use it. Maybe 2morrow. Thanks.
It is a Stihl brand tach. It is kinda pricey. Here is a link to buy one. If you do some research you may be able to find a cheaper one. amzn.to/3qbpUn4
Hey Matt, Walt here. What can ya tell me about pick up coil/ fly wheel magneto adjustment? Should they're be signs of mild scratches on the flywheel side of the pick ups. Not sure my terms are spot on. Been a while. But I got the concept. I'm old enough to remember points. I could keep ya busy for a while on that subject to. What do you know about Wisconsin Motors. Fortunately I'm not that old. But had a cement mixer that run like a champ for a while.
Sounds like you still have the limiter cap on your screw. They're there just as a way to stop inexperienced people from blowing up the saw with incorrect settings.
Single screws are reverse thread. There is no individual adjustment for high and low. Turn it all the way in (counter clockwise) then turn it out two full turns. Start the unit, and turn the screw eithwr direction until you reach the desired idle.
My saw is gutless. When I full rev it no load its fine when I put it to the tree It dies, off tree revs up load on it again it dies. Anynhelp appreciated
got a 171 , this the first saw that keeps readjusting it self ,so when I sqeeze the trigger in the handle it wants to die , a mechanic adjusted it for me but after a while it does it again, I know its one of the screws on the right hand side. why does it reoccur ,, is there not a way to lock it? hope to clear up the above 2 questions, thanks
@@tatsngrass thanks for your reply, we have used it lately but we had t rev it high and that happy setting .but now and than still stalling .but starting not realy a problem .what you thing I likely need to do? turn screw driver anti clockwise or clockwise?
Stihl recommends a MAX of 12,500-13,000. I'd keep it down to 11,500 for general firewood cutting and 12,000 at MOST if you want to have a chainsaw race.
They make a tool for that. I will try to find it and leave a link for it. It can be a pain in the butt, but you can pry them off with a smaller flathead screwdriver.
Im able to start and idle my saw but it bogs on throttle. seems to stay that way either screw i adjust one at at a time. Carb is clean and fuel is fresh, what could be the problem on the ms210c?
The first thing i would check, if you haven't already is compression, needs to be around 120 psi. if that is good, the next thing I would check is the screen in the muffler. Sometimes it will plug up and cause the unit to not throttle up. If that is good, then the carb might need a slight more adjustment on the high side. The factory installs a limiter cap on the adjuster that sometimes needs to be removed to get the correct adjustment to run properly. However, you want to be careful not to go too lean with it or you could burn up the motor.
To All, 10-4 on the spark arrestor, I use all Stihl products all arrestors have failed over time. I don't clean them I throw them where they belong, in the GARBAGE. Life is good again.
Replaced the fuel line that goes into the tank & carb with a new one that came with the carb kit. What do you mean by lines collapsing when under a load ?
Could be a few things. Carb could need a slight adjustment, check the spark arrestor screen in the muffler, coil could be cutting out on a load, or it could even be a dull chain. Hope this helps with the diagnosis of your unit.

Great video had to fix a trigger to carb and one fixed had to reset the trims and idle I appreciate you taking the time to educate all of us.
Thank you. You went over everything three times. Couldn't get any clearer
O29 and o29 super runs perfect both my saws are marked one turn out for baseline you made it simple👍👍👍
O21 runs perfect buddy thank you
One of the best explanations. Thanks.

I have this saw and the spark plug is constantly wet/black , will this adjustment make it run correctly?
Very good video, very helpful good to know the settings. enjoyed watching this video. Good luck and Thank you
Great help thank you
And if you don't have the rpm gauge tool?
Those are the jets you’re adjusting right?
Thank you !
Thank you for mentioning those locks not telling me how I need to get them on or off.... ...........
Wow... Simple amazing.
Ok how do u tune it outside of the stupid limiter caps. With limiters... it runs wayyyyyy tooooo lean
Hopefully this will work 2morrow. My 025 pops, then it poops. Been struggling with it for a year. Still have yet to be able to use it. Maybe 2morrow. Thanks.
Your video is very informative! Thanks for making it.
Can you tell me the rpm gauge you used?
What type was it?
It is a Stihl brand tach. It is kinda pricey. Here is a link to buy one. If you do some research you may be able to find a cheaper one. amzn.to/3qbpUn4

How to Adjust Carburetor start idling then stop when eccerating
great video. id like to know what initial setting do you start from with idle screw
On most stihl units, i start at one full turn out on the low side, and 3/4 of a turn on the high side
on the idle screw, i just turn it up a little so the idle is a little high. not really any certain setting to start.
Should the idle screw start all the way in or out. Where did you get that tac
In
I can't find the rpm gauge either, everything on eBay has a wire and doesn't look like his.
Why don't anyone work on MS171 Stihl chainsaw
why my starter is too tide
How do you adjust the stihl when the piece of junk wont start never mind run.
What brand rpm meter do you recommend?
/bump
what do you set LA at though before you start?
exactly my question
You can’t turn the low screw “one full turn” it only turns 3/4 maximum
Sounds like you still have the limiter cap on your screw. They're there just as a way to stop inexperienced people from blowing up the saw with incorrect settings.
i have a ms 170 but there is only one screw and iit idle too high even when i set it the lowest possible
Single screws are reverse thread. There is no individual adjustment for high and low. Turn it all the way in (counter clockwise) then turn it out two full turns. Start the unit, and turn the screw eithwr direction until you reach the desired idle.
@@avalanchereviews2352 thanks a lot man hope it's gonna work!
My saw is gutless. When I full rev it no load its fine when I put it to the tree It dies, off tree revs up load on it again it dies. Anynhelp appreciated
I had a saw do the exact same thing and it boggled my mind.
I cleaned the air filter and changed the fuel filter and it helped a lot
got a 171 , this the first saw that keeps readjusting it self ,so when I sqeeze the trigger in the handle it wants to die , a mechanic adjusted it for me but after a while it does it again, I know its one of the screws on the right hand side. why does it reoccur ,, is there not a way to lock it? hope to clear up the above 2 questions, thanks
I would pull the screw all the way out but pay attention to how many rotations it takes to get out and apply loctite
@@tatsngrass thanks for your reply, we have used it lately but we had t rev it high and that happy setting .but now and than still stalling .but starting not realy a problem .what you thing I likely need to do? turn screw driver anti clockwise or clockwise?
kiwi farmer anti clockwise should give it more fuel and increase the revs. The bottom screw adjusts idle
So 2800-3000 idle and 12,000-12,500 full? Definitely going to get an rpm reader. I have a Stihl 271
Stihl recommends a MAX of 12,500-13,000. I'd keep it down to 11,500 for general firewood cutting and 12,000 at MOST if you want to have a chainsaw race.
What if you don't have that tool that you showed
Amazon has them, maybe $10
Where’d you get the rpm reader
amzn.to/45OjEVJ
how to take off the blocks?
They make a tool for that. I will try to find it and leave a link for it. It can be a pain in the butt, but you can pry them off with a smaller flathead screwdriver.
@@avalanchereviews2352 thank you
Right. So I will look for a TH-cam that shows how to do it on the forest

had a similar problem and it turned out to be a plugged spark arrestor in muffler
To All, 10-4 on the spark arrestor, I use all Stihl products all arrestors have failed over time. I don't clean them I throw them where they belong, in the GARBAGE. Life is good again.
My 023 starts, but falls down when full throttle when hot ...
Check your fuel lines. Lines could be collapsing when under a load.
Replaced the fuel line that goes into the tank & carb with a new one that came with the carb kit. What do you mean by lines collapsing when under a load ?
If the lines are soft sometimes they will squeeze and close up under full throttle
@@avalanchereviews2352 my 023 didnt have a spark arrestor, fuel vent line doesnt leak 🙃
the chainsaw has no power, the chain stops in the wood, what would be the cause?
Could be a few things. Carb could need a slight adjustment, check the spark arrestor screen in the muffler, coil could be cutting out on a load, or it could even be a dull chain. Hope this helps with the diagnosis of your unit.
Is 180° considered a "full turn or 360° ?
1/2 of a full turn
@@avalanchereviews2352 so is a full turn 360°?
@@fmolds yes
Stihl ms 231 won't rev up to its full she will stop
