MAXIMUM THROTTLE SPEED ADJUSTMENT
In many cases on variable speed applications, a drive
pin is used as a maximum speed stop on the governor.
In this case, the drive pin is located on the opposite side
of the throttle bracket as shown in Figure 5. This would
be in the approximate position of the arrow head on
reference D.
To adjust this type of governor:

2. Breaker Assembly
a. Breaker points are operated by a cam on engine
camshaft.
b. Dirty contact points can be cleaned with
gasoline. Wipe dry and make sure that no lint
or oil film is left between breaker point surfaces.
c. Pitted or burned points should be replaced. See
Timing Section for proper setting.
