    pull out the 3rd circuit air bleeds, drive it and see how it does. if it cleans up alot, leave the bleeds out. remember, when you're setting idle on a dominator, you HAVE TO ADJUST BOTH IDLE SCREWS THE SAME AMOUNT don't just adjust the frt and think you're doin it right, cause that's not right. my mixtures screws are all 4 about 1 1/2 turns out.

    nutha thing i've noticed about dominators, they like alot of timing at idle to get the vaccum signal up. i'm locked at 36 and after the initial warm up, i can idle around all day and never have to tap the throttle to start the boat warm.

    Bolt on a Holley R8082-1 and never look back. Just changed out some 3 circuit 1050's to 2 circuit, like driving a new boat. Idles, accelerates, no 4 cycle in mid range (3rd circuit fuel dump) no black soot all over boat. Call Tom @ Holley Tech > 270-781-9741 ask him about 3 circuit in your application. The 3 circuit carb has some extremely long idle slots, so changing metering blocks (making your carb 2 circuit) just creates a new set of problems.

    Very good point Tom!
    That could fix his idle and surge problem depending on were his timing advance comes in.

    Surge (lean or timing) maybe a little differant than a thrid circuit (rich) blubber.

    I have duel 3 circuit dominators on my boat, and with a little bleed swap it works great at all throttle openings. And like you said, tap the starter button and it fires right up.
    I ended up with 80 intermidiate bleeds to clean it up, and a little idle screw adjust. The timing is locked at 31*.
