Description:

In 1964 Fairbanks, Morse Inc. changed its name to Colt Industries.

Abstract:

The ignition system for providing spark ignition to the cylinders of an internal combustion engine includes a generator assembly adapted to be mounted on said engine. This generator assembly includes a magneto adapted to be driven in response to the operation of the engine to provide output power and a timing unit including at least one rotatable unit driven in timing relationship to the operation of said engine. A control assembly is removably mounted on the generator assembly and incorporates an ignition control circuit connected to receive power from the magneto and operative in response to the timing unit to provide spark ignition to specific cylinders of the internal combustion engine. The control assembly is removable from the generator assembly without altering the timing relationship between rotatable unit and engine.
