I've been running my 505" with a Dominator on the street. It's always been a little rich (after putting in aftermarket metering blocks, before that it was WAY rich). I've been playing with it a bit lately and I seem to be making large changes in jet sizes for little change in A/F. The tuning forums suggested to start with a 85/95 jetting (with PV in front) as a baseline. I'm now at 78/88, and my A/F suggests I should still jet down further. Other specs are: Transfer slot restrictor: 0.055" PV channel restrictor: 0.089" Idle feed restrictor: 0.040" Idle air bleed: 0.082" Main air bleed: 0.026" Also has a high flow 6.5 PV in the primary side. Anyway, I thought I'd ask to see how people have their Doms jetted?

it's easier to find the proper changes by logging some ifo and posting it. idle rpm and a/f # off idle and a/f # no load 1500 rpm a/f loaded 1500 (cruise) rpm a/f etc. etc. i doubt you actually need a hi-flow power valve. i've never found it necessary on an 8896 dominator for street use.

I've installed .035 restrictors in the idle fuel and transfer fuel slots, it is way to lean now when cold, 15.9 to 20.+ depending on throttle position. this is a 9375 non HP two circuit that has been modified a bunch before I bought it, no power valves. I do have two other 9375-2 HP 3 circuits 1050 Dominator carbs., trying similar idle fuel and transfer fuel restrictor sizes to get a good part throttle cruise AFR, 14.2 or leaner
