Odd Engine

Anyone seen one of these?

Looks like it would have to have a rotary valve with the carb mounted to the crankcase, Suzuki made motorcycles with the carb inside the case with a rotating disc as the valve. How the one in the picture works would be interesting.

Probably a reed valve being front mounted. As I remember the older bikes with the rotary valves had the carb in the case on the engines side. I believe the original Russian engines had the carb case mounted also. Looks like the muffler is on the front also next to the carb? Is the big round object a wheel hub that inserts into the hole in the engines case? Looks like it may have spoke holes? What ever it is its pretty weird.

I wonder what its for, looks like a pass through gear box for a keyed shaft, I've worked on conveyor reducer made that way.

No. Looks like it would be a nightmare to mount it on a bicycle.

Looks like its designed to be mounted under the frame, possibly using the pedal shaft to help hold up the engine. Kinda like those old Ducati Cicolo units, except 2 stroke.

It’s interesting anywho

Looking at the hub on the left, I am beginning to wonder if its actually a "motorwheel kit"
