ABSTRACT:
A flyweight assembly and a manual speed control member are connected through a linkage to a control rod which controls the fuel injection volume of the pump so that the control rod position is determined by both the flyweight assembly and the control member. Idling and main counterforce springs resist movement of the flyweight assembly in their respective engine speed ranges. The control member is arranged to bring a spring mechanism into engagement with the idling counterforce spring when moved beyond a certain point to demand higher engine speed. The spring mechanism acts against the idling counterforce spring to move the control rod to reduce the fuel injection volume when the speed control member is moved from its idling speed position to demand rapid acceleration while the idling counterforce spring remains engaged with the flyweight assembly to prevent excessive fuel injection volume.
