Ok so im having an issue with my new 351w thats been running rich.This is a new motor.Its a 1972 351w block with stock ported heads comp cams 512 hydrolic flat tappet cam performance products intake and a quickfuel 750 carb.The car starts and idles fine but you smell fuel and if you look under the car its just smokey in general.My fuel pressure is weird.I am running a holley fuel pressure regulator into a summit dual feed line.I have 1 fuel pressure gauge on the summt line by the carb and the other on the fuel pressure regulator.Now if i have 3psi at the regulator i have about 13 psi at the summit dual feed line.If i have about 1psi from the regulator im running 7 1/2 psi by the dual feed.Why is this?Which is most accurate?I dont know what else to do in this case.I looked at my quickfuel calibration sheet and it says the following
Pri Jet: #74
Sec Jet: #84 W/Jet Extensions
P.V. Pri: #45
P.V Sec: Plugged
