HESITATION STUTTERING AND CUTTING OF WHEN ACCELERATING

1984 Mitsubishi Mighty Max • 1,000 miles

Just had engine rebuilt now when I press the gas the truck hesitates and sputters. If u pres the gas hard it cuts off or there is a pop that will come out of the carb sometimes but a pop always comes out the tailpipe when u press the gas hard. Other then that it starts fine idles fine but does hesitate and jerk when driving. It doesn't pop (backfire) when its cold and u gas it only once its warmed up. BeBesides the engine rebuil I replaced fuel fuel pump, fuel filter n air filter. The accelerater pump seems to be working when the engine is off and I gas it. I'm at a loss please help

Did you replace all the basic tune up parts?

Only other probs I can think is carb needs to b replaced (I hope not hear bad stuff about the mikuni rebuilds) or cat is worn out or possibly muffler
