Around 1975 or so I used to resurrect dead sno sleds. Had one that the crank rusted pretty bad. Just did gaskets and seals and I ran the hell out of it for a couple of seasons. Sold it and bought another carkus to save. Made that rolling noise real loud.
Real long story short..rebuilt 2cyl motor. Out of 7 rods I acquired various ways only 2 were not bent or kinked. One from 76′ motor and one newer style rod were good. New pistons used larger pin. Press out old bearing with outer race to use with larger pin. New bearing and pin but with generous clearance on the unused small end race. Other rod newer style was tighter at the pin even though it was run on.
Just curious if I could hear the loose one rattle….
