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
