I have a 1972 Road Runner GTX that runs great, except when it sits for longer than a day or two. It is a well-kept original car, original carburetor, the engine and trans have never been opened, etc., less than 30,000 miles. The last time the carburetor was rebuilt was in 2018, and the fuel pump was replaced at that time, but it exhibits the same problem as it always has: if the car sits for more than a few days, say two weeks, it is very difficult to start. There just is no fuel at the first, second, or third crank. I can understand this for the first start after sitting for months during the winter, but not after days or a few weeks. Here is what I do to start it: I press the accelerator to set the choke, turn the key to engage the starter, crank for 10 seconds or so, stop the crank, pump the accelerator pedal, crank again, repeat several more times. Usually after the fourth or fifth time of this procedure it starts. then it runs great. Hot starts are instantaneous, as are warm starts. The car does not hesitate or buck when cold.
Does anyone have any ideas on how to fix this problem? Thanks.
