65 fastback bogging out
I just picked up a 65 fastback that used to be a show car back in the 70s. It has a 289 with a mild cam, roller tip rockers, and a torquer open intake with a Holley 600 double pumper. When you first give it gas it bogs out and wants to die, but once you give it a little more gas it's fine and revs up. We checked the front accelerator arm and someone told us it was stuck so we took the front bowl off and replaced the accelerator pump diaphragm and the power valve. We got it back together and the arm works now but it's still bogging out when you give it a little gas. I don't mess with holleys I've always ran edelbrock so if anyone knows what it might be, all help is appreciated, Dom.
