HELP!
while the 066 was waiting for the second decomp (i found one screw stripped that holds the top cover on and that might have been letting the cover viberate and break the decomp button, although thats a streach) to arrive i was fiddleing with the rotation of the flywheel and found some rotational roughness. i removed starter cover, muffler, plug, decomp plug, and clutch housing and roughness remained. then i discovered a round metal ball (about the size of a # 6 shot) lying on the block where the muffler would be and after shaking the saw another fell out from somewhere. there is no endplay in the crank. the remaining roughness is when the piston is top dead center like the piston is hitting the top of the jug and then buckling past the "bump". before the second steel ball fell out i was occasionally getting a crank lockup other than the top dead center one. once the second ball fell out the crank rotates fine except tdc. piston looks fine from exhaust port and plug holes but i have not popped the jug.
saw was running fine when i last shut it off.
what the heck is going on? this is another first for me.
any info appreciated thanks in advance 1953greg
