make sure your timming is set right , and check plug s and put exstended jets in the rear. you might be pulling your fule away from the jets and make sure your floats are set up, becuse if not your bowls will run dry before the fuel pump can pick it up. whats your fuel pressure at are you running a tank or fuel sell mabe you are puttiing all you fuel at the rear of the tank and it cant get any till the car levels a little .??
