Ms 180 won't idle

Hi

Well as per title I have a ms180 that approx 10 years old

Won't idle starts from cold fine, few pulls and it's away. Seems to rev fine but as soon as you go to let it idle it cuts out and won't start again unless you give it a touch of throttle.

Any ideas or pointers be great

Cheers:thumbup1:

The old MS180s had a strange idle adjuster, it isn't a mechanical stop on the throttle valve but a screw that adjusts the amount of fuel flow against a throttle valve that is held open in a set position.

 

That being said, try adjusting up to 1/2 turn one way and the other and look for the idle to be stable and not spin the chain.

 

Also check nothing is binding the clutch drum to the crank - make sure it spins freely as twine and crap can get around the clutch and cause drag on it against the crank causing stalling.

 

Did the saw struggle to idle with the chainbrake on before the idle went?
