Since it's dead in here, let's talk about secondary air door opening.

Seems that this is one of those things that is surrounded by myth and urban legend (like most q-jet tuning "Secrets"). I would guess that larger openings flow more CFM. I also wonder how much large openings affect mixture distribution, and once you start increasing the opening angle, the flap starts getting closer to the discharge tubes. Has anyone found a "best" setting for secondary air valve opening (as measured from choke horn). Does it really matter that much in a practical application?

EDIT: I see we did discus this here:


Does anyone have anything to add?
