Something is definitely up with this carb. Maybe blown PV or something. My transition slot is squared up on the primary and closed on the secondary. I just tested the car went from 73# to 76# then 79# on the IAB's made hardly any difference at all. Do you know what size IFR's come with these carbs. I installed a 29# didn't seem to make much of a difference either. Does the IFR regulate fuel or Air when installed at the top on the Emulsion with these quick fuels. I thought it was fuel but doesn't fuel enter from the bottom and air is introduce from the top where the restriction is currently installed?
