I'm bored and am thinking of playing with my poulan/craftsman 3800. I've got squish down to .022. Comp is 135lbs with new rings and less than 1 tank used. I've heard that advancing the timing by filing the woodruff key will liven the saw up. Question: do I file the left side of the key and move flywheel clockwise, or do I go the other way? Will this even accomplish anything?

Bob,
Filing either side of the key will accomplish the same thing.
Filing the RIGHT side (looking at the top of the flywheel) of the keyway in the flywheel will move you counter clockwise and advance your timing.
My recommendation is that you just cut a sliver off a 1983 or newer penny and use that for your key. It is completely reversible that way and doesn't disfigure a $25.00 flywheel.
The width of the key on some saws won't make much difference, on others it is way too much.
Best to go slow and try it (with a stopwatch) then go a little farther if necessary.
