I need a little help with a stock flathead-single 94-stock distributor, mech fuel pump in a 50 ford I just bought. The carb has been cleaned, has stock jets and has a new fuel filter. The accelerator pump works. I haven't checked the timing yet or the points but i suppose that's my next stop. The car hesitated when stepping on the gas. If I step lightly on the gas, it will make it up through the gears (slowly) but, if I stomp on it, it continues to stumble. I thought it was the float level. I set it to the correct level (it was a little low) and put the throttle plate lever linkage back in the middle position (it was in #1). I hopped in the car and went down the road. All seemed well, the car accelerated perfectly. I thought I fixed the problem. I parked the car for about 5 mins, went back to the car and I'm having the same problem. The only thing that could have changed in that time would have been temperature and possibly the gas. Even though i have a filter I don't know the condition of the tank. One other weird detail, someone wired in an electric fuel pump w/ a switch. I have no idea why. Any thoughts?
