Carb Tuning 1993 185 OMC Cobra Holley Carb

I've got a 93 Chris Craft Concept 185 running a 3.0L OMC Cobra Sterndrive w/a Holley Carb... I think that I need to adjust the carb, when accelerating from idle (after in gear), engine hesitates (and stalls if I push it). Once it get's past the initial hesitation it runs great. Also if running on a hose out of the water it rev's just fine. Any tips on tuning the carb?

2 Barrel, I gather? Did you do a vapour leak test on the carb at idle? The Carb solid? I'll make the guess of the week and say 1 1/2 turns out from softly seated to start.Choke set ok? Electrical ok?
BTW...DONT rev it up out of water. The engine does not get enough water. Only IDLE.

I would say it sounds like rebuild time, at least for the accelerator pump on the carb. It gives an extra shot of gas while the carb is switching over from low speed to high speed circuit so that you don't have that hesitation and stalling problem.
