This patent describes a speed limiting governor for use with an engine having a throttle movable between an open throttle position and a close throttle position for regulating the flow of fuel to the engine. The governor is of the type comprising an overriding throttle closing means, and engine speed signal generating means for producing a signal corresponding to engine speed, a load speed signal generating means for producing a signal corresponding to load speed, actuating means including a reversible motor coupled with the overriding throttle closing means and being responsive to motor control signals for energizing the motor in the close throttle direction or in the open throttle direction, logic means responsive to the engine speed signal and the load speed signal for producing motor control signals for moving the overriding means between a wide open throttle position and a close throttle position and to intermediate positions including a reference position. The logic means is responsive to the speed signals for moving the overriding means in the close throttle direction to the reference position when the engine speed reaches a first preset value, and means responsive to engine power demand for energizing the motor to move the overriding means from the reference position toward the open throttle position.
