The title sorta says it all...
-SPOILER ALERT!- Keep reading if you want to know what the engine is!!!
I ended up buying a complete Rotax 245 RV motor off a complete stranger from another country ONLINE... It's the engine from a 1976 Skidoo Tnt RV 250. I was quite excited to get my hand on a complete 250 engine because they are relatively hard to find. Upon first inspection the vintage Rotax appeared to be complete with dual Mikuni carbs, Polar fire (Bosch) CDI ignition, wiring harness, belt, clutch and recoil.
The rare 245cc twin cylinder free air engine appears to be in quite good condition, except for the fact that the rotary valve was jamming at half revolution. Removing the cover solved the issue and further repair will be require. The pistons looked new, so a complete overhaul will not be likely, but a teardown, cleaning and gasket replacement will be next for this Rotax. The crank seals will also be replaced.
If you enjoy old vintage race sleds, dIY projects, mechanics, repairs and working on old junk, you have come to the right place. I hope you enjoy this video!
