It's a Kawasaki 292b motor used in the early 70s, 22hp. Easy to find parts for. It's so close to complee I have to try to get it running in original form. There's a few vintage sled guys in upstate NY, I'll see what they have. Only missing a carburetor and master cylinder cover.
I have a nice set of 22" knobbies for the other project, basket case Ruppster. But its not a differential rear, so the smoother tread might be kinder to my yard, and maybe rubber mount the seat.
The 22hp seems a little scary. Been meaning to get to Winber, maybe good goal for 2025, get it running and bring it.
