I just picked up a couple saws. One is a Pioneer Farmsaw from 1981. From my research it turns out to be a 66cc which is perfect for my 1/3 Laser! Seems to have good compression but haven't checked for spark yet. Had to tear it apart to find the number plate. Has anyone ever converted one of these saws? It has the crankcase built into the saw body and is magnesium. Should turn out to be pretty light. May go gas/glo anyway.

The other one is a 45cc Echo that will work well on my Stinger 120.
