Here are pictures of an engine I own, that I know to be at least fifty years old. A neighbor used it to run a washing machine for several years and 1 purchased it from him over forty-four years ago.

This engine has neither name, number or specification plate on it anywhere. The engine stands 11? inches high and sits on a round base 5? inches in diameter that also serves as a fuel tank.

The bore is one and five-eighths inches, the stroke one and seven-eighths inches. The rod is bronze, 4? inches in length, the wrist pin 3 eighths and the crank pin ? inch in diameter respectively. The fly-wheel is 8? inches across and 1? inches wide. It is cast iron and the spokes cast iron fan blades. The crankshaft is what I call a hall crank. It has only one counter weight on the crank case end and of course the fly wheel on the other. The crank pin slips through the lower end of the rod and screws into the small side of the counter-weight. The piston has a taper lop and carries two rings ? inch wide each.

The ignition is obtained from a battery and a buzz coil. The movable contact point is a spring loaded brass wiper arm mounted on one fan of the fly wheel. This in turn makes contact on a fiber stationary ring mounted on the crank shaft housing. The fiber ring has a brass insert at one spot, and of course when the movable contact on the flywheel comes in contact with the insert ignition occurs. The spark plug has a taper base, the same as used in the old model T Ford.

The engine is 2 cycle and the unique tiling about it is the carburation. The piston has a taper head but this acts only as an exhaust valve. The fuel is drawn from the tank in the base through a brass tube to a mixing valve, and from there through a pipe nipple to the side of the crank case. The fuel then enters the crank case through two ? inch openings directly behind the crank shall counter balance. Mounted on the crank shaft between the counter balance and the crank case wall is a spring loaded bronze washer with two openings that match the two in the side of the crank case, thus every revolution of the crank shaft opens and closes these holes twice, there by acting as an intake valve.
