This is a recently finished Stihl 066. I’m having trouble tuning out the the run-on as the saw returns to idle and the off-idle bog.
The saw is ported with machine work. Complete rebuild. Meteor piston. 461 coil.
It will idle all day. It seems like it settles into that idle nicely, but only after a lean run-on for 1-2 seconds. Is this carb or coil? Outside chance of a crank issue? Tank vent?
