Carburetor rebuild still didn’t fix the problem!!!

So my car (73 Fury III with 2B 400) has been bogging down when on the interstate doing about 80. It seems like it does it during hotter weather. If I am taking off from a stop up a hill and I press down too far on the pedal it bogs down and I have to lay off and feather the pedal for a while otherwise it still “stutters.” I have to keep the air cleaner lid flipped upside down to let more air in because if I don’t it will die out eventually and it won’t start until I flip the lid back over...
