need help with a Holley carb

Lance, as far as the fuel pressure is concerned, I don't know if the guage is bad, weak or what. I don't know how accurate it is. It has a Carter M6907 pump on it and it says the range I believe is between 5.5 and 7.5 max. It is less than 3 years old and only has about 3000 miles on it .What do you check the pressure with other than a new guage. It is probably a good idea to get one.

I have a temporary gauge I T-d up in a spare piece of rubber line that goes between the pump and the carb specifically for testing fuel pressure . after I test it I put my regular fuel line back on. my stock pump is almost exactly 5.5 right where it should be. if the pressure is too high the pump can force fuel past the needle/seats and flood the float bowls. you could try another gauge. I would definitely look into the fuel pressure, that may be where your initial problem started. you could always get a regulator to knock the pressure down, or look into a different fuel pump.
