Ignition Points Timing Question

[happysaws]

I've read how opening the ignition points on a chainsaw a few thousandths should slightly advance the timing, and in turn should make a saw have more high end rpm's, but will advancing the timing with the points make the coil overheat? I would like to try this with a few of my vintage saws, but don't want to ruin the coil, engine, or anything else. Any imput is appreciated!

Shouldn't make any more heat, no. Advancing the timing too far always runs the risk of putting a hole in the piston, though.

I opened the points from .015" to about .019" on an old Remington. It seemed to make a bit of a difference with high end rpm, the saw still starts easy and accelerates quickly. I run 16:1 mix, should the richer mix help prevent from burning a hole in the top of the piston? Thanks much!
