Carb issues with a new Holley 94

[yahbut]

Well I tried the propane test and could not find any leaks. I install two new fuel filters, one before the electric fuel pump and one before the carb, when I install new carb as well as new fuel lines and had fuel tank cleaned and sealed. I wondered about fuel pressure cuz I do have electric fuel pump. The old carb was doing the same thing as this one only acceleration was bad and hard starting and ran rich even after a carb kit. When I bought the car it just had electric fuel pump so I thought possibly too much pressure and was causing these issues. So I put the rod back in the stock fuel pump, hooked it up and had electric fuel pump running through stock fuel pump. I had the electric fuel pump on an on/off switch and only used electric when car sat for awhile for better starting. Anyway after all this work the car didnt run any better. Then just before I bought the new carb I noticed fuel leaking out of gasket on stock fuel pump so I said screw it. When I put new carb on I bypassed stock fuel pump again.
I had the top off the old carb at least a dozen times setting the float...infact I almost had the slot wore out on screws. Thats why I finally bought the new carb. The new Denis Carpenter carbs are all run and tested before being sold.....I hear ya about even though its new it still might need float set......I just dont want to get started with that cuz id hate to wear the screw slots out on the new carb
