This relatively new saw has a problem with idle not dropping sufficiently. I removed the air cleaner cover and discovered that the throttle is not closing all the way when the trigger is released. I can reach in with a small screw driver and push it shut with a gentle push. It doesn't seem to be the throttle valve itself as I can open it by reaching in and pushing on a tab (on the disk attached to the throttle butterfly shaft) and it closes fully by itself. (That is, opening it without using the trigger.) The trigger itself seems to release fully too. There is a throttle cable connecting the trigger and disk on the end of the throttle butterfly shaft. I suspect that the cable is sticking or may be missing a return spring.
The previous owner (seller, actually) did O/H the carb to solve a problem with the power piston.
I thought I'd ask here for suggestions before I start taking it apart to figure out what's sticking and fix it.
thanks,
walt
