My 73 stalls when I first push the pedal from a stop if I don't give it gas very gently, and when I am coasting and go to give it gas it will also stall. The stall in both situations is only for a brief second when I give it gas quickly (but not stomping on it) then it catches. Stock 302 with original carb, auto trans. I have recently had the gas tank cleaned and fresh fuel filters as well as checked for vacuum leaks. Any thoughts on what to check next would be appreciated....thanks
