Centering Spring
NOTE:
Adjustment of centering spring is extremely sensitive. Adjustment screw must never be turned more than 1/8 turn in either direction.
Auto-Cruise system is designed to maintain speed designated by driver, within 3 MPH. Speed change is made by adjusting spring centering screw. If speed control holds speed more than 3 MPH above designated speed, turn centering spring screw "C" toward "S" but only 1/8 turn or less. See Fig 1. If speed is more than 3 MPH below designated speed, turn the centering spring speed screw "C" toward "F", but only 1/8 turn or less.
