I have a '69 Galaxie with a 390-2V that hesitates when you first press the accelerator pedal. After the stumble, it catches on a runs very strong and smooth, so something is just wrong in the initial tip-in of the accelerator.
I have a nearly new Pony Carbs rebuilt Autolite 2100 in there . . have carfefully timed the car for a smooth fast idle and high vaccum. It doesn't seem like a mixture or choke problem, and since the idle is smooth I don't think it's a vaccum leak.
Does anyone have any ideas/experience in solving this?
Thanks.
