I don't understand that AT ALL.
I have seen Q-Jet throttle plates with drilled holes--almost certainly OEM, although I didn't own the carb from new. But drilling the throttle plates is a third-rate "fix" compared to the idle air bypass.

Yep! Carb was built by Sean Murphy at S.M.I for this engine .... he had aluminum plugs driven into both passages in the main body, blocking off the Idle Bypass completely, but then had an .083" hole drilled in each Primary Blade for Idle Bypass. Makes ZERO sense to me. Cliff told me he has seen that a LOT through the years, with not only SMI carbs, but other commercial "custom" Q-Jets he has had to fix as well .....
