The ethanol in gasoline softens fuel lines to the point they collapse.
Change the fuel lines and use non ethanol gasoline. [ Very expensive]

Try changing the gas filter. Usually down in the tank. Take a piece of wire hook I and pull filter out

SOURCE: Chainsaw starts off running strong gets hot and quits after 10

You might try blowing with compressed air around the cylinder and head to get rid of the accumulated sawdust. Also, the high speed needle on the carburetor might be set too lean--with engine warm, adjust CCW until engine 4-strokes unloaded, but smooths out when lightly loaded (cutting wood). If too rich, it won't stop 4-stroking.

SOURCE: my husqvarna 350 chainsaw starts but wont stay running for more than a few seconds

Eric:

Find the gas/air adjustment screws on the carb (next to the the throttle cam where the throttle cable attaches. Turn the screws in all the way... GENTLY... Those are needle valves, and too much torque on them will damage the needle valve seats. turn both of them out one and a quarter to one and a half turns. Start the saw, and adjust one or the other screw in or out until the saw runs properly. If there is a plastic stop installed on the screws, remove it first, and replace it after the saw is running properly. You have to be patient while tuning the carb as it may take a while. If you adjust too much and the saw refuses to start at all, start over with the 1-1/4 to 1-1/2 turns out on the screws.

Husqvarna 435 chainsaw starts easy and revs up fine. Hold it wide open and has uneven miss. Changed spark plug and cleaned carb. New saw, 1 tank of gas. Also checked seals. Any Ideas


Have you checked the timing gap between the flywheel and ignition module.? If its a NEW saw it should be covered under warranty, take it back to where you got it from and get them to fix it. Are you running it with Husqvarnas bluey green oil.?? That's the first thing your dealer will recommend you use.

I have a huscavarna 435 chainsaw and after running a few minutes the chain locks up


You may have the chain tensioner set a little too tight.

Additional things to check:
  • The sprocket on the end of the guide bar is greased, and turning smoothly.
  • The chain brake is working correctly (not dragging or only partially disengaging).
  • The guide bar is straight, not bent or twisted, burr free, and the groove the chain travels in hasn't been squeezed together.
  • The chain tension is set correctly.
  • The chain oiler is functioning correctly (and you have a sufficient amount and correct type of bar oil).
  • Chain is in good condition, and the correct one for the saw. Make sure all of the links flex smoothly.
  • Chain is sharp. A dull chain will put more pressure on the guide bar because the cutting teeth aren't digging into the wood efficiently (and usually a person pushes harder on the saw when the chain is getting dull).

I have a Husqvarna 435.Hard to start.When it runs, it has no power.It does the same as if it runs out of gas.I loosen the gas tank plug, then it starts and I'm good for 10 minutes.I also have a Husqvarna...


Sounds like the fuel cap on the 435 is not venting properly. Change the fuel cap and do not overtighten. Should correct your issue. The 435 is a nice light weight unit.

How do i set air on husky 435 saw to fix boggy runnin


Mitch:

Adjust the fuel and air mixture screws while the saw is running... you'll find that "sweet spot"... it just takes a little patience! Small adjustments... If you over adjust and the saw quits running or starting, GENTLY turn both screws in all the way (don't damage the needle valves or seats) and turn both out one and a quarter (1 1/4) turns out. The saw should start, then adjust from there.

I have a husqvarna 345 run for a few cuts then stops.


either blocked fuel filter in the fuel tank ( hook out and replace ) or the fuel tank breather is blocked thus causing a vacume in the tank, to prove this, when the saw starts to die slacken off the filler cap, this will allow air into the tank and it should pick up again, the breather is pressed into the tank on the r/h side rear.

I have a 141 that starts fine when cold, but after it runs a while it is hard to start back up again. What is the trick to getting it started again after I shut it off.


First make sure the air filter is clean and if it is try holding the trigger half way open and make sure the clutch brake is on.

Husqvarna 235e will not stay running


Take the saw back for warranty service. We have a Husky #435 that had starting problems when new last year--warranty service replaced the ignition module the first trip, then a little later, they replaced the carburetor--it has worked very well since. I suspect that Husqvarna has had problems with our ethanol blended fuels. Hope this helps!

When the engine gets warm it starts to cut out when sawing, take it off the log and give the engine it seems to sound right, Husqvarna 435 16 in chainsaw


1. Clean the air filter.
2. Drain and refill the fuel reservoir with freshly mixed fuel/oil.

It sounds as though the fuel setting isn't quite right. Don't try to adjust it with a dirty air filter (to lean once cleaned) or stale fuel.
If it still acts up I'd take it to a good local chainsaw seller/mechanic. It needs to be warm before adjusting and if they don't make a cut after the adjustment they would never get my saw again. HTH
