I decided not to use my NOS engine for this bike. I'm gonna save it for the sled restore I originally bought it for, which is a Bolens Diablo Rouge like pictured here.

Here is the nos engine. Still has the factory intake and exhaust covers on it.


I'm going to use this one instead. Needs a rebuild, but these things are rediculously simple.



Quick sit in the frame. She will do fine.

Maybe when the wooden engine mounts are replaced!

Well I'm gonna have to track down an oversize piston. Bore isn't terrible, but not great.

Neat thing about these engines, they are actually designed to turn the cylinder 180 from the factory to suit the situation. Even down to a threaded hole on the opposite side of the crank case to run a hose to the carb for the fuel pump.
