I'm in a serious problem. I blew my 82 Polaris 440 fan cooled, oil injected motor. I'd rebuild, except for the fact that there is a hole in the crank case... It's out of a Cutlass SS. I love this sled and want to put a new or used motor in it. I've looked all across Manitoba, and even some parts of Sask. but have come up short. If there is anyone who can help... PLEASE do! Thanks a million in advance.
