RB,
What they teach down under is physics & how to read, both instrumental in understanding how an air bleed works in a carb.
Not sure if I posted this earlier in this thread, but this is from the Carter Carb book by Dave Emanuel, p. 26. It couldn't be more clear....
'....a reduction in bleed size reduces vacuum signal requirements & fuel flow is more easily initiated'.
A smaller [ not larger] AB starts the system SOONER.
