Side crank engine with magneto
2. An aluminum, upright, air-cooled, 2 stroke cycle, 3600 R.P.M. maximum speed governor, side crank engine with magneto driven by a pin in the crank. There is no name anywhere and the paint color suggests that it might have driven a generator to power a radio transmitter for the U.S. Army. I would like some information about this engine.
