I forgot I had this engine. Just came across it in a box. I vaguely remember something about buying it around 7 years ago... Damned if I remember what it is, though. Not a Zenoah, I'm pretty sure. It has Phelan stamped on the flywheel.

You can see that the carb and exhaust are on the opposite end of the engine from the driveshaft - not a design I'm familiar with.

I remember that it had been set up for powering a giant-scale plane. I seem to remember getting it for a Bud Nosen 1/4 scale Citabria, but then I sold the kit. Guess I thought I sold the engine, too.

Any help is appreciated. I'm going to sell it, I guess, and it would help to know what it is.

Thanks!
