Title: Husqvarna 570 stalling problem
Post by: fstedy on October 06, 2010, 07:21:18 PM
I have a Husqvarna 570 that keeps stalling. When starting I can keep it running by pulling the choke out breifly when it starts to quit. Sometimes if you catch it in a fast idle it will take full throttle ( sometimes when doing this it quits after about 15 seconds, sometimes it will cut a log thru ). I cleaned the air filter changed the fuel filter and the spark plug was checked OK. Any suggestions where to proceed?

Sounds like it's running lean, perhaps due to an air leak somewhere. I'd check fuel lines as well as the impulse line. That's the quick easy possible cause, and quite likely due to the havoc caused by ethanol fuels. You'd think the manufacturers would have introduced ethanol resistant fuel system components before ethanol fuel was forced upon us.  :-\

That'd make way to much sense.

Where is the impulse line? I'm not very knowledgeable about chainsaws.
