99 problems and a Ford ain't one.

I didn't read all the replies but it sounds like you should put a stock fuel pump on it that needs no regulator. And then you should put some brand new needle and seats in the carburetor and it just floats so doesn't overfill and push it into the mains and down the intake manifold. And once you get your flooding issue taken care of with that stuff move on to some ignition tuning. Of course none of that matters if you have a wasted camshaft ...dot. In that case start over.
Most of the time all anyone really needs is a good mechanic.

I just worked on this old guy's 68 Belvedere, Cherry car, red paint job original owner bought it here in town 273 automatic car. He said he had some other guy working on it then one day when he was driving..he went to stop in the car jerked to the right and he almost crashed into a curb. So I took the breaks apart and found little things like locator spring cups for the shoes on the brakes one of them was on the backing plate side spring in the wrong hole Etc, mis adjusted... I fixed it all. It also ran hot...and had a hiccup off he line.... so I put my light on it and found it was about 18 degrees retarded.... so I set it to the factory 2 1/2 degrees and lowered the idle to 650 N...still ran hiccupy dirty...so check the mix on the new reman carb the previous mechanic put on it...1 screw was @2 turns and the other @4 1/8 turns out... in gear idle was 498-512 rpm...I set them each 2 out...then just a hair less...rpm went to a solid 550 in gear...just mixture corrected. No more hiccup and scoots along real good now with its 103k original miles... guy was so happy he tossed me a hundred dollar bill.

Get a good mechanic ...and dont blame the car.
