Re: 3x2 center carb vent control arm and valve mis
MM --- After the introduction of the bowl idle vent, in 1966, it appears that ALL Holley trottle shafts had the extra lever, whether the carb had the vent or not. GM Engineering drawings in A.Colvin's book bear this out. Don't know if this continued after 1970, when bowl idle vents were history.
