AFB carb 525 cfm

I'm having a carb problem. I have a 1964 Dodge 383. The 'carb' is running out of fuel. The pump is a new mallory 250 with the return line going from the pump to the cell. The fuel line is 1/2" to the reg. The mallory reg. fuel presure is @ 6 psi. The carb I have has a stock booster on the front primary side. Whats got me bugged, is on the underside, it has a hole from the factory on the discharge nozzle. AFB has used this type on the 1963-1965 carbs, I think. I have a 4130 off a 1966 and it has a newer style booster with no hole on the bottom, like the edelbrocks. I don't know if this hole is helping or hurting. I have 98 jets in the back. Floats are set at 7/32, float drop is 3/4. Fuel has been a problum since day one with my motor. The last time out, I put a 750 edelbrock on it, and the motor ran fine. I'm stuck running this small AFB. Any suggestions?
