Carb Questions..HELP!

Did anyone ever try the air valve adjustment on it? I have ran quite a few AVS carbs in different applications and never had any bog issues as long as the secondary air valve was adjusted correctly.
Yes we have tried everything , giving up on it , will keep it on the numbers matching block sitting in my garage . I built the motor in it now to beat at the track , guess a 42 year old carb just does not cut it . Most here say holley is going to work best on the track so I.m going for it .
