great thread ;D  other day I was reading a mastermind post where he filed of 20 thousandths off the key to advance the timing on his hotrod saw. my customers ms250 is still breaking pull ropes and damaging starter fingers. if I file 10 thousandths off other side of key to retard timing a little reckon it would tame this saw a little.

Yep it would but just put it back to stock.     I have a few saws also that I have advanced the timing on and you really have to pull them with conviction or else it pulls the handle right out of your hand.   But at the higher RPM's they sure do run.
