(7) Rotate the flat on the linkage rod (lengthen or
shorten) to achieve proper linkage adjustment (Fig.
67). Tighten both nuts after adjustment.
(8) With the engine OFF, operate the throttle
from accelerator pedal and check for throttle lever
action and binding. Be sure throttle lever stop is
against the low idle speed screw after throttle is
released.
(9) Be sure of wide open throttle (WOT) when
accelerator pedal is pressed to the floor. This is
checked by observing throttle lever breakover posi­
tion. Proceed to the following:
(a) Key OFF and engine OFF for this test.
(b) Two people are needed for this test. From
inside of the vehicle, press the accelerator pedal
about half-way to the floor. Movement of both the
throttle lever and throttle lever-to-injection pump
lever linkage rod (Fig. 65) should be observed.
(c) Continue to press the accelerator pedal to the
floor. I f throttle lever breakover is operating cor­
rectly, the throttle lever-to- injection pump lever
linkage rod should have stopped moving while the
throttle lever continues to move towards the rear
of vehicle.
(10) Again, check and verify low idle speed. Adjust
i f necessary.
