Chainsaw Repair

I have not done it on a 361.

From other engines I have done it makes them touchy to start.

The usual practice is to time some cuts - advance your flywheel a half key width and time some more cuts in the same wood and see if there was any improvement?

I suspect the 361 has advancing timing on the original coil and I would not recommend advancing the flywheel any more as it is already at 26 degrees while cutting and that is getting too close to all the advance you would want? At any rate, you will not be able to likely measure any improvement.
