Chainsaw keeps cutting out

[JamesNYorkshire]

Having a similar problem with a second hand Husky 350, it cuts out as soon as I come off the throttle, air filter is clean and have tried adjusting the L and idle screws.

The clutch does seem to be creating quite a lot of heat, though it’s on so tight I can’t get it off to check the bearing...

Don't forget its a LH thread . I find compression  is enough if you make sure the de comp is out . Use a copper or aluminum drift and twat it with a mallet in the right direction of rotation and it will spin off .

Yes, am trying to loosen it clockwise, think I might have get one of husky’s clutch removal sockets and hammer on the wrench for some leverage... 

Do you think it could be a disintegrated bearing that’s causing it to cut out?

Should probably add that I can only start it on “fast-idle” (choke out then in before starting) or whatever it’s called, can rev it as much as I like but as soon as I let go of the throttle it cuts out...

Yes,  it could be. 

But have you considered the obvious? Is the clutch spring weak,  causing the clutch weights to expand / engage the clutch drum at a to low speed ?

I don’t know to be honest, I’m used to stihl clutches and in general I just do the basics of maintenance, it’s one of these kind of clutches.... https://www.lsengineers.co.uk/clutch-assembly-for-husqvarna-340-350-355-chainsaws.html 

and I still can’t get it off anyway...

Had a 346 with the same, clutch centre  split in half across the threads and locked clutch up stalling engine at tick over

[JamesNYorkshire]

Having finally removed the clutch and replaced it as well as the sprocket, needle bearing, air filter and fuel filter it still stalls after coming off the throttle whatever I do with the L and idle carb adjustments... 

Next I’m planning to clean the carb and either clean or replace the muffler... Is there anything else I should be checking that could be the cause of this?

 

Thanks, James

The cutting out sounds like you need to adjust the L screw out a bit for more fuel and then adjust the tickover accordingly.

Are all the clutch springs present?
