A friend had a motor that his father purchased many years ago. It had two intake (exaust ports). The engine is a little larger than an .049 size and has the name "fury" stamped on the left hand part of the prop shaft. Any help identifying this model engine would be greatly appreciated.

Soarbeit, Is there any way that you can get a photo of it? I'm sure that there were a few engines that had 2 exhaust ports, one that comes to mind was a Thunderhead .074 & .11. If we could see it, I'm sure that someone on here could ID it for you.

The engine is a K & B Allen Fury engine. They made 2 sizes an 049 and about an 075. They also made in line twins of both engines. Besides aircraft engines they made marine versions and outboards too in both singles and twins.

I had the 09 and 15 twins. The 15 was a little screamer and smooth besides.
