Servo Unit (Lock-In Screw Adjustment)

NOTE: Lock-in accuracy will be affected by engine being out of tune, adverse power-to-weight ratio, and improper slack in throttle control cable.

If speed drops more than 2 to 3 MPH when speed control is activated, lock-in adjusting screws should be turned counterclockwise approximately 1/4 turn for each 1 MPH correction required. If speed increases more than 2 to 3 MPH, turn screw clockwise approximately 1/4 turn for each 1 MPH correction required. If screw is loose, stake side of servo housing adjacent to screw to ensure a snug fit.

CAUTION: Screw should never be turned more than 2 turns in either direction or damage to servo unit may occur.
