You shouldn't need a regulator with a standard mechanical pump - it will put out 5 or 6 psi which is OK with your Carb. I'd start by checking all your fuel lines / connection points / filter ( if you have one ) for leaks, then look at the carb. Edelbrock has a decent trouble shooting section in their on-line tech help section. Might also check your gas cap to ensure proper venting.
