This is a McVicker automatic gas and gasoline engine
manufactured by Alma Manufacturing Company, Alma, Michigan, USA,
No. 7907, Type 3EE, Rev. 350, 6 HP.

My husband Mike found this engine locally about twelve years
ago. The only history he has on this engine is that it pumped water
on an Indiana farm.

He took it apart, cleaned it and reassembled it. It starts
easily and runs quietly.

This engine is gearless. It has a cam operated push rod, which
is put in line with the exhaust valve from a small piston, which is
lifted by force of the explosion from the power stroke.

When running, the engine’s governor controls the ignition,
so it’s always running on the intake and compression strokes
until the governor calls for power.

The mixer has a constant level of fuel, by a fuel pump.

The McVicker has a round connecting rod, and cast iron fuel tank
in the base. Original water hopper cover, the grease cups, priming
cups, compression relief valve, and cylinder oiler are brass, made
by American Injector Company.
