A 3 circuit will idle just fine as long as the throttle blades aren't open too far.

Off idle is the big problem area for 3 circuit carbs. I usually have to lean them out by 50% on the intermediate circuit.

A wide band is highly recommended when trying to dial in a 3 circuit Dominator on a street car. I wouldn't even try to do it anyother way these days. You'll spend more money on plugs and gas than what a wide band would cost. I've seen a few engines ruined by carbs that are too rich and that is a big time expense.



Yes the 3 circuit carb(as in the 8896) is harder to
tune but with a wide band O2 it is very doable..
you have to have the O2 to get the cruise right..
I found the same as Andy the the mid is SUPER rich
and the mid bleeds help big time... one thing you
have to remember is that each circuit adds on to the
total... as in.. the idle adds to the mid, mid adds
to the wot... no circuit turns off to start another
