V/don,
Agreed! Holleys make great boat anchors. When Edel tested a 600 Holley v a 625 AFB on a 350 Chebby, the Carter made 17 hp more, 17 ft/lbs more..........& used less fuel doing it. This was BEFORE Edel started making the AFBs, & a little known fact, Edel was selling Holley carbs under an Edel part #!
However, in fairness the problem the OP is having could happen with any brand of carb.
