Sounds like its still save-able from your description. I'm not a fan of 'repowers' but if it can be done without cutting or hacking anything and someone could still get it to original condition down the road I dont think it would be a bad thing.
There's lots of Wisconsin motors out there so you may be able to find one pretty cheap. If you look for them they are out there, got a Running TRA10D, for $40 and just picked an S8D up at an auction for $22 in PA that turned out to be a good runner as well I'm putting in my 900.
Dont let the parts for the Wisconsins scare you, 90% of them are still available from the factory (I am a Wisconsin parts dealer)
Have any pictures?
