ELECTRONIC SPEED CONTROL
Read all of Section B and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
Loosen the adjustment nuts on the accelerator cable
bracket. Tighten front adjustment nut till governor bell
crank begins to pivot. Back off adjustment nut 1 turn and
tighten rear adjustment nut. As a final check, with the
gas pedal up, the accelerator cable must be slightly
loose between the accelerator cable bracket and the
governor spring assembly.
The function of the carburetor and governor system may
be impaired if no movement is evident.
If, after adjusting accelerator cable, the vehicle backfires
(indicating carburetor is not closing fully) or shows a lack
of performance (indicating carburetor is not opening
fully), an adjustment to the governor cable is required.
Loosen the adjustment nuts on each end of the governor
cable. With governor bell crank at rest, tighten the out-
side upper adjustment nut till the throttle lever begins to
lift off the carburetor throttle stop. Back off adjustment
nut 1 1/2 turns and tighten the inside upper adjustment
nut. Tighten the nuts at the lower end of cable. Pull
cable to check that throttle lever has full travel (Le. con-
tacts throttle stop in both full open and full closed throttle
plate position).
Check choke function and adjust choke cable if
required. See 'Choke Cable Installation and Adjustment'
in the FUEL SYSTEM section.
If, after performing the cable adjustments, the vehicle
performance is still not satisfactory, proceed to the pedal
box and accelerator pedal area for adjustments.

if any adjustments are made in the Pedal box or accelerator
area, it is necessary to go back and perform the accelerator/
governor cable adjustment again. This
must
be done because
any adjustment made in the pedal box or accelerator area will
effect the cable adjustment.
Accelerator Pedal Arm Adjustment
Lift vehicle using procedures and safety information in
section 'B'.
Confirm the accelerator pedal arm (1) contacts the
accelerator pedal bracket (2) when in the released posi-
tion (Ref Fig. 4 on page M-4). If there is no contact,
loosen jam nut (3) and rotate the rod (4) until contact is
made.
Note that the factory applies a thread sealant to the accelera-
tor rod threads before threading the rod into the clevis.
Tighten the jam nut (3) firmly.
Micro Switch Adjustment
When system is correctly adjusted, the micro switch (5)
in the accelerator pedal box (6) will click when the top of
the accelerator pedal moves approximately 1/2” - 5/8”
(13 - 16 mm). The accelerator cable (7) (as seen at the
rear axle) should have some slack present and not show
any movement until after the micro switch clicks.
To access micro switch, loosen rocker panel, lift floor
mat and remove access cover (Ref Fig. 3 on page M-3).
Fig. 3 Accessing Pedal Box
The micro switch can be accessed by removing the
screws (S) securing the cover (9) on the pedal box (Ref
Fig. 4 on page M-4). Loosen the setscrew (10) and
rotate the cam (11) to adjust it. Adjust to permit 1/2” - 5/
8” (13 - 16 mm) of travel at
top
of accelerator pedal
before the micro switch clicks. Make sure the setscrew
in the cam does not contact the micro switch actuator
