Had problems cold starting my 512 sixpack and hesitation on acceleration. Discovered that the accelerator pump arm on the middle Holley is so stiff that the tab from the throttle mechanism has bent to the point where the pump isn't being operated. Still pumps (then starts) with strong manual pressure on the arm. Before I strip it down has anybody had this and what causes it? What spares should I get before stripdown?
