With the engine now assembled, it’s hard to appreciate the fine work in the pistons, rods, crank, and camshaft. Note also the tiny oil pump and pickup.

4-Cylinder Coyotee Engine
Despite the fact that Jim first started this engine in 1964, the Coyotee finally won First Place at the 2002 Gas Engine Antique Reproduction Show (GEARS) in Portland, OR.
Single-Cylinder OHV Engine—“Lil Red”
Single-Cylinder Lil Red Engine
This project started in 1994, when the Coyotee had been completed, but Jim was unable to get it to run. Jim built this engine as a “proof-of-concept,” to show to himself that an engine this small could actually run. It has about the same piston size as the Coyotee.
Single-Cylinder Lil Red Engine
By early 1995, Jim’s Lil Red engine was running. He then went back and applied what he had learned to the 4-cylinder Coyotee.
