ABSTRACT:
An engine governor system includes an electronic governor which controls the fuel supply to an engine in response to an throttle signal supplied by a throttle potentiometer which coupled to a throttle lever. A circuit is connected between the throttle potentiometer and a potential source. The circuit includes a normally closed foot-operated deceleration switch connected in parallel with a first variable resistor, both connected in series with a third variable resistor. Closing the foot-operated switch will reduce the throttle signal by an amount controlled by the adjustment of the first variable resistor. The maximum possible throttle signal can be controlled by the adjustment of the second variable resistor.
