Look at the site above. It was known by Cox as the Beaver. It was sold as an RC engine by Hobby Lobby as the Rhino 1.4. The engine I have came to me used and with an adapter for using a glow plug in place of the spark plug. I plan to try it with a glow plug on gas/glow and maybe with an electronic CDI with gas. My carb diaphram is FUBAR and I plan to fit a walbro carb on it.
The attached images are some pics I have gathered.
