Thread: Resetting secondary adjustment screw.

  1. #1

    Default Resetting secondary adjustment screw.

    I have a 470 Truck Avenger on a my Jeep 258. I was trying to adjust the secondaries, but saw no change of movement of the butterflies on the secondary side. Is there a way to reset the screw?

    Back off the screw, check the throttle blades are closed, then set the screw about 1/4 turn open from zero. Gary
