stihl 019 stuck on full throttle

[ORclimber]

I dropped a still 019t out of a tree last Friday. It looks ok, but when I start it the throttle is stuck on full. I took the handle apart and the side off the saw and can see the trigger move the throttle lever at the carberatur. When I put it back together it still runs full throttle. Any ideas about what I could try before I take it in to a saw shop would be appreciated.

Since the trigger is in the handle and the carb is in the saw housing, the problem is probably a binding of the linkage between the two. Check all the handle mounts. One or more are probably bent, holding the handle out of line and causing bind when assembled.

Thanks, I went and took a look. The rubber mounts fit into the molded plastic housing so there isn't anything to bend. I think the throttle cable is binding up somehow where it enters or winds through the case, is frustrating. I'll fiddle with it tomorrow some more.

The cable type throttles are sometimes troublesome about returning to idle. Sometimes it takes rigging up a second helper return spring.
