Design and development

An Aeronca C-2, with the E-107 "flathead" engine

The E-107A was a production aviation flathead engine designed to replace a Morehouse engine on the first prototype of the Aeronca C-2. The first five were produced without cooling fins on the crankcase, but with all versions having air-cooling fins atop the cylinder heads, similar to many air-cooled two-stroke engines in appearance. A Winfleld Model 5 carburetor was standard for the engine.[2] The E-107 was replaced by the uprated, overhead valvetrain E-113 engine based on the same design.[3]
