NOTE
I
The linkages that control the accelerator mech-
anism, governor and carburetor are designed
to operate as an integrated assembly Any adjustment to one
portion of the system will have an effect on the other compo­
nents within the system.
When the accelerator pedal is depressed, the accelera­
tor rod moves towards the rear of the vehicle by over­
coming the resistance of the accelerator return spring
(Ref Fig. 1 on page F-1 ).
As the accelerator pedal moves, the parking brake is
released, the micro switch closes and activates the igni­
tion circuit.
The rear end of the accelerator rod is joined to the con­
trol arm link, which in turn is attached to the control arm
with a pin which slides within a slot in the control arm link.
As the accelerator rod moves to the rear of the vehicle,
the control arm rotates and pulls the accelerator cable.
When the accelerator cable pulls against the accelerator
cable/governor spring, the spring compresses until it
overcomes the resistance exerted by the governor mech­
anism and its extension spring, the carburetor torsion
spring and the friction of the linkage rod ball joints. As the
accelerator cable/governor spring overcomes these
forces, the governor bellcrank moves and the motion is
transferred through linkage rods and bellcranks to the
carburetor throttle plate.
