What are some of the gains and draw backs from advancing or retard the ignition timing?  Also what is the purpose to do it.

When advanced. You can gain some hp. But the saw may run hot and kick back when pull starting.

Are the best gains on a ported saw or a stock saw? How will you know if you went to far advanced.

It all depends on the saw also. The ms201T gets good gains. A ms660 gets good gains. I heard some saws it does nothing.... What others and myself are doing is shaving off half the fly wheel key and advancing it that much. As far as which gets the best gains(stock or ported) i cant answer that.

How many degrees do you think that is with shaving half key down. Do you shave the whole key or just what sticks above the crankshaft. And yes the 201 does get some good gains. I did advance the timing on mine. Yes just trying to figure out what it made the engine do.

Take away half the width of the key in order to advance the flywheel that much.

I see what you are saying. Does advancing the timing on a 361 give good gains.
