OK so I have a 74 Super, 1600 DP, 34PICT carb (new), and pertronix distributor(new). I've followed carb initial setting instructions, adjusted the valves, has new plugs and wires. I've never cracked the case open but have new pistons, jugs, connecting rods and heads, also all new exhaust. Here's the problem: the car starts but will only run if I keep the throttle close to wide open, as soon as I let it return to idle it dies. It appears I have good fuel flow as the see thru filter is full. Do I have a bad air leak some where or is there another possibility? I just ordered new intake manifold boots. I had the same issue with the stock dual vacuum distributor. Any help would be great as I'm pulling what little hair I have left out.
