the 2 idle air bleeds in the lid top, meet in the same passage along with idle fuel from the idle jet tube,
the air bleed passage comes together into one passage, and exits in the primary venturi area here,
this is the diminishing air bleed exit. air passes through this bleed at low speeds, and fuel comes out at very high rpm, thereby short circuiting and shutting off idle fuel at the baseplate discharge holes/slots.
