Ok i tried a fuel regulator...that didnt help,,,all that did was bring the fuel pressure down...The Phenolic spacer did help with starting the car when hot...the carb stays nice and cool....BUT IM STILL GETTING THIS DAMM STUMBLE ....i put a vented gas cap on too...because i didnt have one...could it be igniton? i see the fuel pressure gauge drop tho like 1 psi then re-gain back to the right pressure again....It doesnt do it all the time seems to do it in 1st and 2nd gears the most never seems to do it on the highway at all...Tonite going to get gas it did it a few times....i was low on gas seemed to do it more .....Im LOST...if i knew what it was i would have fixed it by now...this is killing me.........
