Governor Lever Adjustment |
This
is a cut away view of the governor of a P7100 pump. Notice how the lever hit the
cam plate flush at the very bottom edge. To check your adjustment the throttle
lever needs to be moved until the lever just touches the cam plate. With the AFC
housing removed, look down through the opening behind the cam plate and see where
the lever is striking the plate. This should be done with the Fuel Shutoff Solenoid
in the run ( or pulled up ) position. Where the lever strikes the cam plate will vary depending on the style and design of the cam plate you are using. For plates similar to the stock plate, like shown below, this lever is set correctly. It is adjusted so the lever is flush with the bottom edge of the plate, and does not ride under the plate. |

 For
cam plates, like a TST #6 for example, that have a taper at the very bottom of
the plate, adjust the lever so the lever hits at the tip of the bottom nose on
the plate. It is OK to be slightly below that. However too far down causes the
lever to be held back as the RPM's rise. This causes the loss in bottom end power,
with the sudden surge as the lever finally clears the nose and hits the main fueling
curve.This is what the pump looks like from the back with the cover removed. Do not change the adjustment in the upper right hand corner. The adjustment in the lower left hand corner is the one to make. Loosen the locknut ( 10mm socket required ). Making very small adjustments to the screw, adjust the lever the proper height. Now tighten the locknut. |
