If this is the wrong place for this post please move.

I have a Husqvarna 55, 15 years old & has run just great until now.

Starts & runs great, that is until it warms up, then it stalls as soon as I reduce throttle. eg Finish Cutting one log, lock chain & place on ground while I move log & it stalls.
Only way I can start it again by applying throttle, or by leaving it until it cools down.

Weather permitting I will get more details today.

Any suggestions really appreciated
