SPEED CONTROL

Read all of Section B and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
B

Governor Operation

Until the vehicle reaches its governed speed, the vehicle
will continue to accelerate in relation to the accelerator
pedal position. When the governed speed is reached,
the ground speed governor in the rear axle assembly
operates against the governor spring and closes the car-
buretor until the correct governed speed is achieved
(Ref Fig. 1).
It is the force of the governor spring in response to
accelerator pedal and governor arm position which con-
trols the position of the carburetor throttle plate. This
spring cushions sudden changes in throttle linkage posi-
tion to provide smooth power transmission.
Driving above governed speed could cause a
loss of vehicle control and possible injury or
death.
Tampering with or adjusting the governor or other speed
control components will void the warranty.

TROUBLESHOOTING

Erratic acceleration and performance that does not
include a notable increase in governed speed, may indi-
cate the need for a linkage adjustment.
Symptoms that include an increase in governed speed
indicate:
• A possible governor failure within the rear axle.
• Worn components in the governor system.
• Improper adjustment of linkage system.
Other factors may effect the performance characteristics of the
vehicle but they should be investigated only after confirming
the linkage adjustment.
