Got the engine from a buddy that loves arctic cats & he sold it to me. The sled itself I remember the fellow that had it new as a 640 & remembering drooling over it. Sat for a lot of years & another fellow bought it & was just stored never rode. Third owner is where I got it from and he rebuilt the engine with NOS parts. I know this because we worked together as mechanics back in the day. He rarely ran it because of a bad fuel tank. Took me a couple of years to get him to sell it. Now its up to me to hope to bring back some former glory. Still looking for a tach for this project if someone has one to part with.
My brother stumbled onto a 70 771 engine last year.the owner said it was used to run a waterpump or sae of some kind i cant remember which it was.Crazy
Good luck on the tach hunt.i been hunting for a few years.always eludes me.
