Chrysler — Sensitivity Adjustment
Adjustments · King Seeley governor
From a Chrysler operator's manual covering: IND. 52, IND. 53, IND. 54, IND. 56. Check it applies to your exact model before use.
Procedure
- If governor is too sensitive or has tendency to surge, place hollow wrench on calibrating nut.
- Insert special adjusting wrench through hollow wrench into adjusting screw and turn screw clockwise one turn.
- With hollow wrench in slot of calibrating nut, turn nut clockwise about 1/8 of a turn.
- Hold adjusting screw from turning.
- Continue until surge is eliminated; engines operate most efficiently when governor adjusted to point that just barely eliminates surge at full throttle.
