This circa-1908 Elyria gas engine is one of the more unusual gas engines at the Coolspring Power Museum. It has a conventional 4-cycle design, but mechanically there’s hardly anything like it.

Unusual features of this engine include the three main bearing construction, where there is a main bearing on each side of the crank throw, as well as a bearing outboard of the timing gear but inboard of the left flywheel.

Other features of the Elyria gas engine include an unusual volume governor on the throttling system, as well as the original Bosch integral-coil igniter plug, which is an electrically open set of points powered by a low-tension magneto.

This particular engine powered an Amish sawmill/millwright’s shop near Danville, Pa.
