Type IV Governor (1) Bumper spring (2) Screw (3) Cam lever (4) Bolt | |
Bumper spring (1) is used to improve idle stability. Unlike the bias spring, the bumper spring preloads the tolerances to the fuel on direction at a low rack setting.
Cam lever (3) rotates and the spring touches screw (2). This preloads the governor linkage to the fuel on direction. At a high rack setting, bumper spring (1) has no effect.
