Today i removed the engine from my airframe and took the heads/cylinders off. This engine has a 76mm counterweighted crankshaft and 88mm cylinders (the really sharp ones). This engine differs from the other monnett-converted engine that i have in that it has a steel prop hub. The other one has a 69mm crankshaft and an aluminum prop hub. Also, sadly, the magnet ring is missing from the flywheel, but the electro-x stator remained. Wonder if i could obtain a new magnet ring from some old riding lawnmower flywheel or something.

Anyway heres a few pictures. The top of the case is stamped, and the heads had no casting numbers inside the valve cover, just a few stamped numbers.

Here is a cleaned up picture of that stamping.
