3. FUEL SYSTEM

[1] GOVERNOR

The governor serves to keep engine speed constant
by automatically adjusting the amount of fuel supplied to
the engine according to changes in the load. This engine
employs an all-speed governor which controls the
centrifugal force of the steel ball (1) weight, produced by
rotation of the fuel camshaft (5), and the tension of the
governor spring 1 (7) and 2 (8) are balanced.
