I just installed a new Holley 80457SA 600 cfm carburetor with electric choke on a stock 68 Roadrunner 383 manifold. When starting I have to crank and crank while trying different things with the pedal. First I pump it once to the floor and let up before turning the key. But it just cranks, so I pump again thinking it needs more fuel and it still won't start. Finally it starts after pumping a couple more times with the throttle at different positions (including wide open). I don't know if it's getting too much fuel or not enough. The accelerator pump seems to squirting fuel when checking under the hood and choke sets closed.
So how many times should I have to press the pedal at say 55 degrees ambient? This is very concerning with a new carburetor straight out of the box.
Please let me know what you think.
