I JUST REPLACED THE FUEL TAMK FUEL PUMP AND FUEL LINE ( FRONT TO BACK ) AND INSTALLED A NEW HOLLY CARB, NOW WHEN I START THE CAR IT STARTS RUNS FINE FOR 5 MINUTES THEN STARTS TO SPUTTER AND STALLS AND RESTARTS AND DOES THE SAME THING, ALMOST LIKE IT HAPPENS AS SOON AS IT GETS HOT? ANY IDEAS?

Check timming then you may need to adjust air fuel ratio. First set timming then set rpm then with a vaccum gague attached and a tach. Adjust one side at a time turn screw until max vac and highest rpm repeat other side. This should help smooth out when it is cold the choke riches up, mix when it comes off carb maybe to lean.
