Both levers at the trans. should be facing up. The large lever is the gear selector, the small is the down shift. The cable attaches at the downshift lever with the adjusting end attached to an arm on the throttle shaft. Start engine and allow to get up to operating temp. and the choke is completely open. Idle speed needs to be correct before adjusting cable.
Apply emergency brake and chock the wheels. Adjust the idle speed to spec with the engine in the "D" position or the position which gives all three forward gears. Make sure that the choke is fully opened.
With the engine turned off, check the accelerator pedal for a height of 4 1/2 inches measured from the top of the pedal at its pivot point to the floor pan. To obtain correct pedal height, adjust the linkage at the point where the accelerator shaft meets the acc. connecting link shaft in the vacinity of the carb. This is the pivot point at the end of the acc. shaft. You will see a threaded section at the end of the connecting link with a locking clip. (This procedure for the linkage is for the 6 cyl application as well as V8).
With the carb choke in the off position and engine off, depress the acc pedal to the floor. Block the pedal to hold it in the wide open position. Rotate the downshift lever counter clockwise to place it against its internal stop.
With the lever held in this position, and all slack removed from the cable, adjust the trunion so that it will slide into the accelerator shaft lever. Turn it one additional turn clockwise, then secure it to the lever with the retaining clip.
Remove the block to release the acc. linkage. That should do it.
