Hi....My Guess, it`s in the Carb ! Bepending on what type of Carb You have- It`s either the POWER VALVE or Bad Accelerator Pump. Check those out & Let Me know what You find out. Have a Good One, Dave

thank you for your advise, yes the carb was out of tune , I readjusted it and it seems to be running fine now....the plug wires were fine , the carb was running too lean .....its a 600 cfm Holly carb , I also advanced the timing a lil
