I am running 8896-2 on the street. 500' 440-3 intake. Idle and midrange runs eye burning rich. I am running a progressive linkage and front butterflies open 1/3 before the rears start to open. Carb originally came with 1 to 1 soft progressive.I am running a 4.5 power valve in the front. plug in the back. Found my number 1 & 2 spark plugs black, back six are brown. Idle screws all 4 are set for highest vac. Could using a power valve be causing this? I have an air bleed assortment but have not changed anything yet. Wide open jetting is close. Its idle to about 3500 thats rich. Timing is at 36, have tried it all over the place, it seems to like 36. I am running an aftermarket 10degree bushing in msd with light springs. Idle timing is 26.

Buy yourself some billet metering blocks so you can tune the carb. A Holley three circuit Dominator probably needs to have the intermediate circuit reduced by about 80% to run it on the street at part throttle. Get yourself a wide band setup so you know what your AF ratio is.

An 8896 is not designed to be a street carb. If you're going to try to run one on the street then you need to at least be prepared to completely retune the fuel circuits. You are trying to make that carb do something it wasn't designed to do.
