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