Anyway, I am building a half old style and half new style saw. Split the case on an old style 066, put ceramic bearings in it, but the gasket was toast and my dealer did not have one.
So I jimmy rigged a new style gasket, put the case back together. The bearings spun the crank like it was a dream.
Put a new style tank on, metal flywheel, piston and cylinder kit - matching tri-ported muffler and face plate.
Went to put the clutch back on and notice a crack on the end of the crank where the e-clip goes. I tapped it and half of the end broke off.
Some how whoever removed it banged it and cracked it up. Tried it anyway and to no avail was I able to get the clip to stay on.
My so called gasket rip won't work anyway.
So I just order and new gasket and seal kit and good used crank.
When all is said and done I will have an old style saw that looks new. New style starter cover, chain cover, MS660 top cover, new style tank and big dawgs.
I'll let ya know.
