I was helped with the identity of this engine by the good people here at ACSCC.

The motor is not running, has a spark issue but rolls over OK. The recoil is missing as is the outer cover of the primary clutch. The carb and breather assembly are there and a secondary clutch which I believe goes with this engine are included. However, the clutch may have been altered as this was put into a Kitty Cat at some point. There is a little exhaust manifold too.

Asking $100, or will trade for a CCW 225cc engine or other parts for a 72 Auto ski Midget. I haven't figured out how to put pics here, but they can be seen on my Kijiji ad and I would be happy to send anyone better pictures if requested.
