1050 80340 marine carb 2 circuit. Motor is 572ci 9.25 to 1 compression, 5 inch exhaust, dart 345 heads, roller cam 139651 632 lift, 96 square jetting, 6.5 power valve in the front primary and 6.5 power in the back valve in the secondary.
That is where I wound up with the carb. Also 71 air bleeds were in the idle circuit which went to 57 and finally ended up at 51s. Idles perfect in and out of gear perfect.
I had Barry grant 1090s which if anyone wants a deal on these carbs I have 2 with 10 hrs for $600 each paid a $1000.

Nocig,
Most of the post here are referencing set ups on 2-circuit Holley's. If your Braswell prepared carbs are 3-circuit (the 3rd circuit adds WAY too much fuel in the mid-range), none of these 2-circuit set-ups will apply. Many, including the experts like Bob Teague, have given up trying to get 3-circuit Dominators to work in a marine application.
If your carbs are 3-circuit, consider getting Braswell to change out the metering blocks and convert these carbs to 2-circuit. I am pretty sure this can be done and is an easy fix.

On the top of the carb are a series of brass screw in air bleeds; they look like fuel jets. On the top front and top back of the carb there are are a series of these air bleeds. If there are 6 air bleeds front and 6 back you have a 3-circuit; if there are 4 air bleeds front and 4 back it is a 2-circuit.
