Lean idle. Rich cruise.
Nope, smaller air bleed starts the system sooner.

Bewy, the book is wrong.
You can watch the A/F ratio on the dyno and visually SEE the boosters… wait a minute…did I write it backwards?
No, I wrote it correctly.
A bigger MAB will start the booster sooner because at low air flows the MAB acts like an emulsion bleed.
I have it correct.
That book is wrong. The author either never read the Taylor books or he read them and still got it wrong.
This is one reason guys get what you call “Holleyitus”. Big air bleeds start the booster sooner. They go rich down low and lean up top.
It’s simple to remember.
The bleed that makes the A/F ratio richer at high air flows has the opposite effect at low air flows.
