Auxiliary Rod Tech:
The auxilary power piston uses one metering rod and one fixed "jet". A 50B rod has a large diameter of .058" and a small diameter "power tip" of .050". The .058" section of the rod is positioned in the fixed metering "jet" during light throttle driving. During heavy acceleration, manifold vacuum decreases allowing the auxiliary power piston to rise positioning the smaller diameter (.050") power tip in the fixed metering "jet". Rochester products started using the auxiliary metering rod in 1975.
