Abstract

A method and system for controlling a light-duty combustion engine and, more particularly, a method and system that use an engine speed governor to limit the engine speed to a level that is less than a clutch-in speed of a centrifugal clutch. If it is determined that an operator is attempting to throttle or accelerate the engine, the engine speed governor is disengaged so that normal operation can commence.
