Crusty free poly 318 and where it came from.

You could use a newer snowmobile ? That thing looks like it's had it's day ! :poke:
:D I put over 250 miles on that old 1983 Polaris Indy 440 since I bought it for $150 in January. Rebiult the carbs, cleaned out the tank, ran new fuel/oil lines, cleaned the mouse nest out of the fan cooling shroud, and put a windshield on it. I have a habit of making old stuff work it seems.
