Rebuilt Carb causes "chug" "chug" at ignition

[Gearhead999]

I'm just the oposite, I've had nothing but good luck with AFB's. It's the darn Holley's with their leaks and power valves that drives me crazy.

I had Holleys on my Donzi and later Cigarette. They'd blow a power valve and I'd be out there rocking back and forth changing the power valve so I could get home. Had to idle through the "no wake" zones. With the blown power valve, it was hard to keep it idling without loading up.

I switched to AFB's, a little triming and not a problem.

Also, ran dual 500's on my last Mustang and am building a 347 now with dual 500's.

To me they are much easier to tune and hold the tune better.
