Step in the rod changes the effective jet area between high and low manifold vacuum conditions
Circuits are checked for proper sizing and the calibration is checked for proper jets, primary and secondary metering rods
Description
The Metering Jet is designed for use with the Performer Series and Thunder Series AVS carburetors. The jet and rod is changed to get the cruise air / fuel ratio leaned out. The step in the rod changes the effective jet area between high and low manifold vacuum conditions.
