SPEED CONTROL
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings
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 oper­
ates against the accelerator cable/governor spring and
closes the carburetor until the correct governed speed is
achieved (Ref Fig. 1 on page F-1 ).
It is the force of the accelerator cable/governor compres­
sion spring in response to accelerator pedal and gover­
nor bellcrank position which controls the position of the
carburetor throttle plate. The compression spring pro­
vides cushioning of sudden changes in throttle linkage
position to provide smooth power transmission.
AwARNINGA
Ta mpering with or
adjusting the governor
or other speed control
components will void the warranty.
Driving above governed speed could cause a loss of
vehicle control and possible injury or death.
CAUTION
If the governor requires service, the
service must be performed by an autho­
rized E-Z-GO service branch or distributor who will reseal the
governor after calibration.
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

NOTE
I
Other factors may effect the performance char­
.
- acteristics of the vehicle but they should be
investigated only after confirming the linkage adjustment.
GENERAL LINKAGE ADJUSTMENT
PROCEDURE
The following are the general procedures for removing,
adjusting and installing linkages. Refer back to these pro­
cedures when indicated.
CAUTION
When removing or installing the linkag­
es to any of the bellcranks or levers,
use extreme care not to bend or damage the bellcrank or lever
arms.
Linkage Removal
To remove the ball joint socket from the ball joint ball,
place a 3/8" open end wrench on the jam nut and rotate
clockwise until the socket separates from the ball (Ref
Fig. 2 on page F-2).
Fig. 2 Linkage Removal
Linkage Adjustment
Remove one end of linkage as previously described.
Loosen one jam nut. Hold linkage rod with pliers to stabi­
lize (Ref Fig. 3 on page F-2). Rotate ball joint socket as
necessary to lengthen or shorten until hole in socket
aligns with ball. Tighten jam nut. Reinstall linkage as
described in following procedure.
Fig. 3 Linkage Adjustment
Linkage Installation
To install the ball joint socket to the ball joint ball, support
the arms and squeeze the components together (Ref Fig.
4 on page F-3).
CAUTION
Failure to observe this method of instal­
lation may cause serious damage to the
governor, carburetor or other components and cause expensive
and time consuming repair.
