throttle hesitation
Does anyone actually install a Holly Avenger 670 carb on a Ford 302 crate and see if it runs correctly before selling the damned things? Backdraft #324 was ordered with that set up and from day one it has hesitated when given throttle. I did every possible adjustment, from float levels to increasing jet sizes and nothing helped. Finally out of desperation, I had it dyno checked. Sure enough it was'nt getting fuel. We upped both primary and secondary jets (way up, 6 numbers on the secondaries) installed a new metering block, and power valve spring, and changed the vac advance spring. $800.00 later it feels like a different car, and is actually fun to drive. Needless to say, someone dropped the ball somewhere, and I feel there ought to be at least some effort spent on testing these problems before the cars are sold.
