Re: P41 saw spark plug gap

Bob,

The timing is set by the key in the flywheel which I'm guessing you have in there.
I see you changed your flywheel. If you have the old one make sure the magnets are in the same location and have the same spacing on the old one and the new one.
I don't know if any of the flywheels in that series have different timing but will fit on the crank on your P41.
I would guess that if you are getting smoke out of the muffler you are getting spark but maybe at the wrong time.

You can change the timing by removing the key and rotating the flywheel counterclockwise to advance and clockwise to retard.
I don't see a spec for the timing in the repair manual.

When you had it apart did you check the reed valve to make sure it isn't broken and that it seats well?

The repair manual calls for a plug gap of .030"

let me know if you need a copy of the repair manual for your saw.
Tim
