So the air valve acts like a VV! I have always loved these carbs (and hated a few) and now with greater understanding my love deepens. Agreed- awesome engineering!

bd, you are always a wealth of information! I would love to hear the backstory of your relationship to GM. Thank you sir!

Thanks BD for the great explanation regards the opening of the secondaries, sort of suspected it was something like that but always good to know!
I'm trying 68's in the primary now as it was still a bit rich, hope it doesn't go lean as I don't have any 70's!
