Not in over my head [ post #27 ]. If you do not understand the simple principles involved, then all you are showing is your ignorance.....
Are you aware that Rat Bastid who is trying to tell us how air bleeds work is on the Racing Fuel Systems website asking questions about air bleeds.....

Yes, I ask a lot of questions. Most of which are over your head. I’ll say this a different way so maybe it will connect with you. The MAB an low air speeds acts as an emulsion bleed. That’s why it only changes the fuel curve at higher air speeds (through the booster). If it was you think, a bigger air bleed would lean the fuel curve at ALL air flows. It doesn’t. A smaller MAB will make the fuel curve richer at higher air speeds, not across the fuel curve. Once again, you ignore the change in viscosity of the fluid in the main well. You can see a similar result adding more emulsion bleeds or area or both. You can get enough air in the fuel that it goes dead rich everywhere because you are pulling more fuel sooner. Keep adding emulsion after that and you will get into “slugging”. You will pull a “slug” of emulsified fuel and it goes rich and then you will a lean spot. You can continue to ignore fluid viscosity. And you will still be wrong. I’ve made this as simple as possible so maybe you understand. And yes, I ask questions when I don’t know the answer. Notice I didn’t ask you. There is a reason for that.
