Have a home made primer system on car and trying to figure jetting. Simple pump with solenoid to prevent pulling fuel thru pump and a bar in hat that has 4 holes ,one over two ports spraying up and letting air pull into cylinders. Works fine for firing car, not so well when mechanical pump and electric are both one. LOL Would like to get car to point I can drive up to staging on primer and switch to mech. before doing burnout . Anyone have good starting point for jetting. I can jet in front of spray bar using main jet. Have a .065 but it is way off.
