This patent describes a governor for 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, a control means including engine speed sensing means, and actuating means for moving the throttle closing means to a position for limiting the engine speed to a predetermined governed value, the governor being of the type which requires electrical power supply for operation and including an electrical conductor for supplying electrical power to the governor from a power source. The improvement comprises: holding means for arresting the overriding throttle closing means against movement in the open throttle direction, and control means for operating the holding means to arrest the overriding throttle control means in response to interruption of the supply voltage to the governor, whereby movement of the throttle in the open throttle direction is prevented.
