I bought this engine off ebay because it looked very much like a miniature version of the twin cylinder, simultaneously firing WWII era drone engines that I've been restoring. The two cycle OK Twin is piston-ported instead of rotary valve induction, but the rest is very similar to the Righter designed drone engines. After trading certain parts, I got it to run. All fun for me. Tom
