Pull the flywheel and check the coils on the stator. My early 70's 'Rude
snowmobile used to have those coils expand and crack. Same as some of those
vintage O/B's. I got a couple of replacements off wrecking yard rudes.

Admittedly I'm not as familiar with the snow machines, but I think the
V4 has a different system. The cracking was a problem with some
under-flywheel high tension magneto coils of the vintage 1 and 2
cylinder JohnRude outboards and Lawnboy mowers, i.e. not the V4.
Problem would show up on or after a foggy night or morning when the
motor would not start or would miss till the moisture was heated out
of the affected coil, and/or it would start fine but after the coil
would get hot it would arc and misfire.
