Acceleration problems

[$MoneyGreen]

Hello all. Im new to this forum, as well as a rookie owner of a 70 Chrysler 300 with only 20,000 original miles. I traded it for a similar age Ford 100. Everything is working great on this rig, except some acceleration problems. I starts well, but if I step on the gas HARD, she dyes. If I give it slow and steady gas then it runs fine. The carb is a Carter 4640, and is in good shape. Please help with any ideas. Thank you

Super nice car. I would start with checking the accelerator pump by pulling the air cleaner off, look down the carb and opening the throttle. You should see a big squirt of gas. If not the pump seal could be shot. If that looks good check the timing. I would check the timing anyway because it is a new car to you.
