My coil was fine as tested with the test plug. The 1/4 turn in (clockwise) on the needle eliminated the smoke. I think my throttle was sticking some. I pushed the round adjustment collar down slightly on the airvane. This seemed to help with govener adjustment. It needed 2 turns clockwise to get to 3100RPM. Maybe you need to reset the throttle spring as well. Do you have a repair manual for guideance?

Bring on the leaves. Nothing better than the Mulch-R-Catch for mulching.

Let me know how it goes.

Heres a link to the service manual just in case.

thx for getting back.....2 questions for you.....when you said you checked the spark from the coil with the test plug....did that give you any indication if the run side of the coil was fine too?.......also what kind of tachometer did you use to know that you reached the 3100 rpm level....thx
