GOVERNORS, MECHANICAL DESCRIPTION AND OPERATION
The mechanical flyweight type governors can be used
on these engines. They are belt-driven from the front
of the engine.
A direct mechanical linkage from the governor throttle
control lever to the carburetor throttle lever limits
carburetor action to the governor setting. As the
engine speed increases, the rotation of the governor
shaft increases. Centrifugal force causes the weights
to move outward as the rotation of the governor shaft
increases. However, a spring retards or limits the
movement of the weights until centrifugal force
overcomes the spring tension. At this time the weights
are forced outward, closing the throttle plates through
the linkage to the throttle shaft.
