Stihl Chainsaw Troubleshooting Guide

&#171 Carburetor Settings for a Stihl Chainsaw

Stihl Chainsaw Carburetor Tuning Chart &#187

  1. Compression Test Can you lift the saw off the ground with the pull rope?
  2. Fuel Test Remove air filter and, spray premix into the carburetor and try to start. Use a 50:1 fuel mixture with premium fuel and Stihl oil
  3. Spark Test Remove spark plug clean with solvent & wire brush. Reconnect plug wire and let plug hang close to engine. Pull the starter rope and look for spark. Dim lighting makes it easier to see. If no spark replace plug and try again. Check off/on switch and wire coming from coil. If still no spark replace coil. (Older saws clean and adjust points first)
  4. If saw runs but, not on gas in tank, check gas tank for old gas. Empty old gas and, look for syrup in the bottom of the tank, if present clean thoroughly. Use carburetor cleaner, gas and a brush that can reach in and not melt. Try to start with fresh gas mix. If it doesn’t start check and replace fuel line and pick-up. If it still doesn’t start remove carburetor and check manifold boot (tube between carburetor and engine). Replace if needed and try to start. If it still doesn’t start remove carburetor,disassemble and clean thoroughly. You may have to soak in Simple-Green overnight. Try not to get solvent or carburetor cleaner on gaskets. Check gaskets. Diaphragm gasket should be smooth and puffy not wrinkled or wilted. If in doubt replace. Carburetor kits are around $8-$15 and include all gaskets, needle and spring. Reassemble (making sure all gaskets are positioned properly) and try to start. If it still doesn’t start replace carburetor.

This how-to works with a Husqvarna, Husky, Jonsered, Poulan, McCulloch, Craftsman, Homelite, Echo chainsaws as well as a Stihl 009, 009L,011, 011T,012, 017, 018, 018C, 019, 019T, 020, 020AV, 020T, 021, 023, 024, 025, 026, 026 PRO, 028, 029, 034, 036, 036 PRO, 036 QS II, 039, 044, 046M, 066M, 088M, MS170, MS180C, MS191T, MS192T, MS200, MS200T, MS210, MS250, MS260, MS260 PRO, MS270, MS280, MS290, MS310, MS360, MS360 PRO, MS360 QS II, MS361, MS390, MS440, MS460, MS660, MS880, HT100, HT101, HT70, HT75

    I have a MS260 about 5 years old. I was happily cutting wood yesterday. I turned it off via the master control lever as always. But now The master conlrol lever seems to be stuck in the off position. I did not want to force it . I had tries to use the trigger at various positions to try to unlock it.

    How can I un-jam it?

  • Tom

    I have a new Stihl MS250. I am trying to start it for the first time but it will not start. I am sure I have set everything correctly. What could I have missed?

  • marljon

    I have a stihl 029 super, it just started to make a whining noise IF I can get it to rev up. Is it the clutch?

  • Ruben

    I have a stihl 029 super, I need to know were the H and L need to be set. I installed a new carburator kit and the adjustments moved.

  • Jerkatrog

    tom try using carb cleaner . spray into carb and let it set for a sec.

  • Dave

    How can I replace gas line on Stihl 009L chainsaw?

  • Alan Sowell

    Mine does the same thing. Take off the cover for the air filter, and push the spring back so the lever will go past it.

  • Jamonson

    I have an 026. When I take the plug out I can pull over the saw easy and can feel suction so the rings are good. When the plug is in you can hardly pull the starting cord. Please give me a possible cause of this problem. This is the best saw I have ever owned. Thanks much.

    Try cleaning out your carb

  • Anonymous

    First thing I’d do is slightly loosen the gas cap. Does it run properly when you do that? If so, your problem is most likely a plugged tank vent – the saw runs fine until it creates so much vacuum in the tank that it can’t suck fuel anymore. then change the gas filter on the end of suction hose in gas tank. You can fish it out with a piece of wire. If that doesn’t help, then check gas line and impulse hose closely for small cracks. Next take off the muffler check to see if the piston is scored from the starter fluid (bad idea use 50:1).

    If none of that helps, it has carb problems:debris in needle valve, harden diaphragm. I would rebuild the carburetor, the rubber diaphragm gets hard over time. Also replace the fuel hose, and impulse hose. disassemble the carb, and thoroughly clean it out, the inlet screen and the passage below the screen, you will have to remove the needle/lever from the other side to blow it out.Replace the diaphram.

  • Anonymous

    Check to see if it has spark when it does that again. Could be a faulty coil. Is the fuel in the tank hot? Boiling?

  • Anonymous

    Do you have spark? Does it start if you put fuel in spark plug hole?

  • Anonymous

    Sounds like a clogged muffler or a stuck reed valve.

  • Ms 361 new spark plug, cleaned fillers, and fresh gas. it starts runs fast then dies?

  • Wes

    I have a 170 and it runs great until I get to 3/4 throttle then it bogs. I thought the chain may have been binding so I took off the blade and it does the same thing.

  • gary123

    why is my chain not getting oil

  • zackk

    check your impulse line comming from the back of the block to the gas tank. if the line isnt cracked check the intake boot.

  • Terry

  • mike

    My 440 won’t start, floods out, turn upside down to clear fuel from clyr and fuel runs out carb.

    I have a ms170 when I start it with the choke on it should die the take off choke and start but it run’s with choke on and when I switch it over to run it dies.

  • Leah Miller

    I have a stihl ms250c chainsaw that when I pull the starter string the wheel attached to the engine just spins, but the pull string still winds up. A local repair shop said it might be the primary or secondary starter spring. How would I replace this on my own?

  • Bryan

    I have stihl 023. Was cutting some small trees and my clutch froze up, Tried to remove clutch, but its not budging.

  • Starrbock

    You may be flooding it, in the cold choked position. This is all the way down on the master control. Take spark plug out and pull cord a few times in with master control in off. It only takes one correctly pulled pull then up to second from bottom is to start engine and warm up a few seconds. Make sure your break is ON. Full throttle. Blip the throttle. To auto go into Runyon, then pull chain break off. Now start and stop in upper positioning of master control rest of your day. I rarely need to go to starting positions needing throttle pressed to get to, lowest two. Maybe second from bottom if engine gets cold, in very cold weather. From here, be careful in lowest master control possition, as smaller Stihl tend to not pop as larger ones and hard to tell the engine turning indicating switch up one.

  • andy ice cream

    I have a stihl 026 that I replaced the coil in because of no spark. It now starts and runs fine but it is running hot. It melted the plastic above the muffler. It has a oregon power pitch plus bar on it. Any suggestion is that bar blocking the oiler? Thanks for the help.

  • redbeard45

    I have an 0-11AV. Sat for a long time and wouldn’t start. Replaced with new fuel, checked exhaust port and muffler – all good, replaced plug. Fired but died when throttle opened. Replaced fuel line, fuel and air filters and gasket under carby. Good spark. After assembly, fired briefly (I think on fuel used for cleaning around plastic mounting block for carb). Won’t fire at all now. Plug is dry. Doesn’t appear to have fuel in impulse line???

  • jrr1

    I have Stihl 029 that I made up new gas and cranked and ran. Wanted to die while cutting but would crank back.Seems to be pressure in gas tank. Ran out of gas and will not crank back. Suggestions?

  • bob

    I have a stihl 034 chainsaw, I bought it brand new, its about 15 years old, I have taken great care of it, it looks good, always run fresh mixed gas and never leave it stored with gas always run it out of fuel, I was running it and it just stopped running, so I put new pull rope on it, new plug, cleaned air filter, filled it up with mixed fuel a new mixed batch, replaced with new electric plug wire box, cleaned entire magneto with sandpaper, it has spark but doesn’t have a lot of kick on end of plug with finger when you turn it over, and it just wont start and run, any suggestions, I have been using and working on saws for 15 to 20 years and my dad has an old 044 or 045 and has been using and working on saws for 30 plus years, and we just cant get it running, I have talked to the guy I bought the saw from and he works on them and he doesn’t no whats wrong, does anyone have any suggestions, I even cleaned the filter in the fuel tank and the vent, also I tried with the brake on and off still nothing, I tried 3 plugs and then I put the plugs in a different saw and they run fine, don’t no what else it could be, I even tried fuel straight in carb and then a touch of starting fluid, also I even by passed the on off switch and tried with and without bar, took off the muffler and all is clean and good, hope you have a solution, thanks

    Ethanol softened hose i get tank on two of my 170’s. Sucks hosd shut and dissolved particals in carb.

  • John Early

    I just bought a used Stihl ms170 at a pawn shop. I got a good deal on it but it wont start. I replaced the plug, air filter and fuel filter. It still didn’t start. I tried to find a carb rebuild kit but found out a whole new carb was only $35 so I bought it and replaced it and it still don’t start. I made sure it is getting spark and getting gas. I cleaned off the screen in the muffler also. I noticed at the top of this page it asks about picking the saw up with pull cord, well the cord comes out before I can get the saw off the ground. Does this mean the compression is bad?? Please help!

    I have a Stihl 025 and no oil is exiting the oil port at the chain/bar. Initial indication was a dry chain. Took clutch / cover off and found wire detached from worm gear that turns oil pump. Purchase a new one and reinstalled. Still no oil. Disassembled and found oil under clutch cover or in that area, but still not get to bar and chain. Pulled oil pump and blew out line to bar/chain with air and seemed clear. Pump appears to be functioning fine. Pump alignment to supply port looks good as well. Still no oil to chain. Purchased a new pump, installed – still no oil to chain. WT ? ? ? ? ?

  • Dude Mauldin

    I have a two year old MS290….from the beginning I have run 40/1 fuel….87 octane….it has worked well but after a couple hours of work, the gear that runs the chain will seize up……I loosen the chain, cool the saw and it rotates again…..however, it finally seized up and will not turn…I move the gear with a channel lock and it sounds like metal to metal inside? but it rotates….any ideas

    I have a 036 pro and it runs wide open. we rebuilt carb and replaced rubber tube behind carb still run wild can you help

  • Wilson Wright

    I have a Sthl MS 170 chainsaw…It was starting hard and curtting poorly…While I had the chain bar off to get the chain sharpened, I took the cover off…I noted a black wire with a metal piece on the end that was loose and there seems to be no place to attach it. I also noted the spark plug was loose. I tightened it and the saw starts much better even tho the black wire isn’t attached to anything…But with the chain bar off, I note the motor seems to be smoking and running very hot. What would cause the motor to run hot and where does the little black wire go ?

  • Gary M

    I have an MS360 which stopped running and it and it jams very hard when I try to start it. I dissassembled and cleaned it thoroughly including the clutch and still it jams. I took out the plug and it pulls freely but under compression jams hard.

Do i need to have it looked at?

    Hi I have a stihl ms192T. It fires up but dies as soon as take the choke off. Carb and gas are good. new plug. the primer would stay stuck at time so I blew it out and it seems to respond properly but wheezes a bit but <i think thats natural. Weird! I just went almost afull tank trying to get it going. Ive set the H mid 3/4 (it is limited to a 3/4 turn adjustment. I set L at 1/2, 1, 1/4 etc but it won't even run long enough for to adjust.

  • gotit

    I had the same starting issue with my brand new MS250. This is what I did in the end. I had the chainsaw on the ground with my right foot supporting the saw through the handle, and pulling the cord with my left. 1st set it to full choke, do 2 good pulls. Then half choke, 1 good pull. And here’s the tricky part. Set it to ‘run’ position and slightly cock your right foot so its depressing the throttle. You may have to cluck the safety first, but once its clicked your foot will be able to pull the trigger. Make sure your.comfortable and put more emphasis on holding the saw!!!! Do a few.good.pulls and it’ll go. I’ve never had to do this again – it was only from brand new…

    I have a STHIL
    MS 290 that appearsto have too much compression. It rips the cord out of my hand…very difficult.Only used to cut the winters firewood. Have had it to several STHIL dealers but they could not find a problem. The problem is still there and there is only a few hours on the saw. When I first got the saw it started really well.If this problem cannot be fixed, I will have to get rid of the saw. Hoping you can help solve the problem because I really liked the saw in the beginning. Thank You.

  • stihlmech

    The lever may have gone past the kill/off switch location. Look on the left side, behind the selector shaft for a silver colored spring steel kill-switch contact. It looks like an upside down V. Use your thumb to push the front part of the V toward the back while moving the selector switch. It should fall into place on it’s own.

  • Ron Elliott

    I have an MS250 that’s worked well for dozens of hours this year. Today, after adjusting the chain tension and operating the saw for a couple of minutes, the chain tightened on the bar to the point that it wouldn’t turn. After taking off the sprocket cover, I could barely turn the wheel (by hand) to loosen the chain. This same sequence happened several times. I noticed when I was sawing that the chain seemed to “grab” the wood rather than cutting smoothly like it usually does. The chain is newly sharpened and the bar is straight. Chain oil is at least leaving the reservoir at the right rate. The thing that’s really got me stumped is that the chain noticeably tightens with use rather than becoming looser. Any ideas?

    i have a farm boss 029 and it will not start. it has fresh gas, i rebuilt the carb and gave it a through cleaning. i checked the gap on the plug it is at .020 and the cylindar compression is at 110psi. using light air pressure i made sure the pickup line was clear but it will still not run. it will run briefly on either. its acting like its not getting fuel but im absolutley stumped, anyone have any ideas? mabye i overlooked something simple.

    I was cutting with my ms 251 and it all the sudden went dead half way through the cut. I tried to crank it but there was no compression . It is about 2 years old. Can anyone tell me what might have happened.

    I just bought a brand new stihl MS 180 C-BE and when I got home and fired it up, the chain did not move. I have taken the chain and bar off to make sure the clutch is actually engaging, and it is. At a loss as to why it’s not working properly. Any suggestions would be appreciated. I will bring it back to the store tomorrow if I can’t figure it out.

    036 saw, starts , idles once warm but I have to have the idle screw all the way in to keep it that way. When I hit the gas trigger it dies unless I baby it in. Ideas? This has been a great saw, made a lot of sawdust!

    I have a 1998 024 Stihl ran it for years first pull cranks, but this year I can’t get it to start. Checked spark good, has good spark had to replace in tank fuel line. (had a crack in it) thought that was the problem but nope. Any ideas any fixes I have no clue thank you in advance.

    I’ve got a 660 m/s Steel chainsaw and it started bogging down as I was running it so I pulled the gas filter and tried to clean it and put it back in and now it only runs on full choke it won’t run it just it’ll start but you gotta have the choke on full

    Hi I have a stihl ms 260c.
    Chain seems too tight when engine running, probably due to the quick stop mechanism not adjusted properly Or sprocket assembly issue? Chain drive sprockets are worn and could do with being replaced.
    Chain running freely on bar as normal when engine stopped.
    Could this be a replace broken/worn parts scenario or would there be a simpler solution?
