2 configured like the old style cast Holley blocks always works. I use 3, but opt for smaller holes .-020-.021 range. Of course I also use different boosters... post 15 Emulsion Tuning
Earlier in the thread is the graph showing what can happen with too much/many air holes in the well.
Too bady Andy F didn't take the good advice provided in that thread.
Halfway measures don't work in a situation like this. When there is too much air introduced, its no longer an 'emulsion'. It doesn't act like a lower density liquid, it acts like a fluid with big air pockets and randomly spurts out fuel in different amounts and densities. And how does it flow - laminar or turbulent? Its a mess.
Way back in the beginning Tuner quotes Klaus about "two phase" liquids. The emulsion has to be a mix of fuel with tiny air bubbles for it to act as a lower density liquid.
