ADJUSTMENT PROCEDURE
Turn ignition switch to OFF position.
Remove air cleaner if necessary.
Disconnect cable end Throttle Valve Cable at Throttle Linkage) from attachment stud on throttle lever. Carefully slide cable off stud. Do not pry or pull cable off.
Verify that transmission throttle lever is in fully closed position. Then be sure lever on throttle body is at curb idle position.
Pry the T.V. cable lock into the UP position. This will unlock the cable and allow for readjustment.
Apply just enough tension on the T.V. cable to remove any slack in the cable. Pulling too tight will cause the T.V. lever on the transmission to move out of its idle position, which will result in an incorrect T.V. cable adjustment. Slide the sheath of the T.V. cable back and forth until the centerlines of the T.V. cable end and the throttle bell crank lever are aligned within one millimeter (1mm).
While holding the T.V. cable in the set position push the T.V. cable lock into the down position. This will lock the present T.V. cable adjustment.
NOTE: Be sure that as the cable is pulled forward and centered on the throttle lever stud, the cable housing moves smoothly with the cable. Due to the angle at which the cable housing enters the spring housing, the cable housing may bind slightly and create an incorrect adjustment.
Reconnect the T.V. cable to the throttle bellcrank lever.
Check cable adjustment. Verify transmission throttle lever and lever on throttle body move simultaneously.
