If it's overfueling, check the needle valve in the carb, and install a pressure regulator in the line between the pump and carb. Set the regulator to about 3PSI.

is 7 psi a problem for this edelbrock carb

I see you have the same post in 2 different places. Which one would you like us to respond to?

See my post above for your answer.

ok silicon212, just finished putting back together the carb and feel that the needle valve problem you suggested is going to be the answer, will know here shortly after test drive, and i will let you know if the result is positive thanks
