Default What engine is this?
I have this engine mounted on a Great Planes 120 Stearman. None of our club members reconize it. The head is tapperd, has rear exhaust, magneto & a spring recoil starter. My guess is a Quadra 42.

It most likely is a Quadra (U.S.engine).

Whatever it is, it screams & flies a Stearman with authority.
