Obtained at the same time and place as another unknown engine, this twin flywheel engine is also interesting in its construction. It features a complicated regulator mechanism within the flywheel and rotary valves. What appears to be an oil filter resides at the rear between the flywheels. The engine is reversible by means of a lever mechanism. It appears to be made from a combination of homemade castings, commercial valve castings, and finely machined bar stock parts. It’s an odd combination; however, the engine is very sophisticated in function for its small size, and it runs extremely well. Somebody knew what they were doing when they built it. Both engines appear to have been built by the same person. This engine, which is mounted on an oak base, was restored by our shop machinist, Tom Boyer.
