Carb tuning help
Moper are you referring to the power valve channel restrictors? If so have you ever measured them or just eyeballed them? I have measured them on several different carbs and have found differences in the PVCR sizes. I've measured them from .035"~.060". There are billet metering blocks on the market that allows you to change the sizes of them to find that proper flat fuel curve.
Exactly.
Moper, I don't know where you got that info that ALL the PVRC holes are the same size, i've worked with many holleys, they are not all the same size, like i've said & will stick to it, Holleys are the most tuneable over other carbs, you just need to understand how they work, we can go on & on, & in the end, if you learn how to tune them, you'll be very happy with them, they are not rocket sience, also as sake of arguement, if the float levels are off on a carter, they too will not work right, most know that, & have exsperience it time after time, same goes for any carb, you need a certain level of fuel in any carb to properly meter the air/fuel, if its too low/high, it interupts the metering. Its fine that you like carters, i like holleys, & most lickly always will, i said it before, & i'll say it again, i HATED holleys back when, that was only because i didn't take the time to understand them, or try & tune them, but when i got lucky with one that worked great on my combo, i was a believer, so i got my act together & read as many holley tuneing books as possible, then got after it, the end results were a ++++, maybe i need to start with an eddy 750 AFB, see if i can fix there quirks.
