Flyweights develop sufficient centrifugal force to overcome the preload of a high speed governor spring when the speed of an internal combustion engine is above a predetermined maximum value to move a fuel control rod to decrease the amount of fuel injection and reduce the engine speed to the maximum value. The flyweights develop insufficient centrifugal force to overcome the preload of a low speed governor spring when the engine speed drops below a predetermined minimum value and the low speed governor spring moves the flyweights and thereby the fuel control rod to increase the amount of fuel injection and increase the engine speed to the minimum value. A manual speed control member moves the fuel control rod to control the engine speed between the minimum and maximum values. A linkage connects the speed control member to the flyweights in such a manner as to limit movement thereof when the engine speed is below the minimum value to a degree which is dependent on the position of the speed control member to prevent excessive fuel injection when the engine is operating under load.
