Hi guys could use some help with hesitation after a wheel stand. The car is carrying the wheels out about 50-55 feet and the hesitation is accuring when the cars front suspension is below static, not in the air. We have tube running from vent tube to vent tube, fuel pressure is at 7, flout levels are good. We tried raising them a touch and lowering them. Oh and yes we have bowl extentions. Pretty sure its a fuel problem, but maybe you guys can give me suggestions. Thanks Eric

Also, check your battery (or batteries) and cables VERY closely. If a battery has a loose plate, the "bounce" will cause it to short out or open intermittently. The "bounce" on landing is also likely to make every connection in the car try to move, so if one is weak, it will move.
By the way, if the battery has dual connections (top and side posts) be aware that those connections should be checked carefully as problems will hide there. Check ALL of your ground connections.

I'm sure you have jet extensions on the rear, but do you think the bowl extensions could be allowing them enough room to uncover? Just a thought. |

Can you describe the hesitation? Does it bang, pop, or miss, or does the engine just loose power without any other sound? Does the symptom occur after the rebound/bounce or before?
I am thinking that if the ignition is crapping out you would experience a bang or pop when the engine comes back to life? Maybe Dave can further describe his situation to shed more light. |

Is this a Superstocker? If so, another idea to toss around is a wedge carb spacer.

I had that same problem many years ago. As soon as it came down there was that ever so slight hesitation then it picked up & ran strong to the end. It turned out I needed that wedge plate as Jeff mentioned in the previous post. Probably was starving the secondaries at the top but I did not notice until it landed.
