261 cm running problem..

[Pinkfoot]

My 261 has a running problem on the overun.

Starts and runs fine , but on lifting off the throttle it comes down to a fast idle before tick over.

Sounds exactly the same as if low on fuel.

Have stopped using it and will take it back to the dealer , still under warranty .

Any ideas?

Air leak somewhere ?

That is a classic sign of an air leak but get it back to the dealer if under warranty.

Any rubber parts such as inlet manifold, impulse line (your machine has it built in to the manifold), crank seals, decomp valve, cylinder loose, carb loose and any mating gasket surface in the crankcase.

 

Air leaks are genefally rare in newer machines, parts generally last 5-10 years before they start leaking unless someone has stuck a screwdriver through a manifold or there is a fault with the saws manufacturing.

Thank you mate. Appreciate it.

Could be as simple as a sticky throttle cable? Or an idle adjustment is needed?

He also said a local tree surgeon plugged his Huskies in that he has had for three years and was really surprised to see they had only done around 50 hours cutting each ,.and twenty idling!
