hey all, i've been having trouble with my 4 bbl carb recently. the only stamp on it says P-32 and i think that's a holley if i'm not mistaken. at idle it doesn't want to stay alive and feels like it's choking on something (either for gas or air) when i'm driving at anything other than WOT. it used to idle high around 1200-1500 RPM, but since i ran out of gas one time it's been giving me trouble, trying to die at idle and on a good day only idling at 700-1000 rpm. any help?
