I’m not sure I would drop the MAB any and if you do make that change, I would do it after you make the other changes. The good news is the bowls don’t have to come off to do that!!!! If you reduce the size of the MAB you delay the booster coming on, and you will make the A/F ratio richer at higher RPM. So the bigger MAB has the opposite affect, which is a bigger MAB will get you on the booster sooner and lean the higher RPM.
Is this right? A smaller MAB delays the onset of boosters? I thought it'd be the other way around, a bigger air leak requiring more airflow to suck fuel through it.
Which brings up another question: Are small main jets and big PVCR affected less by the air bleed at high RPM (than a big jet with a small PVCR)? Or do they behave the same and only the total area is the factor that determines fuel flow?
I'm in over my head here
