This engine is a, single cylinder, air cooled four stroke. It was a two part article featured in Popular Mechanics magazine in 1936 by E.C. Wittick. "Midget Gas Engine" Part 1 was making the wood patterns for the aluminum crank case and the cast Iron cylinder and flywheel.
Part 2 was "machining the castings" In the article there are pictures of the engine in a model boat.
The bore is 1-1/4". The hardest part of this engine is getting the valves to seat properly in the head, and then machining the cam shaft. All of the parts were sand cast in my backyard in a very small propane fueled furnace. The machining was done on a South Bend 9" lathe.
