Rich,

I have an original AFB from a '63 New Yorker, and another original AFB 
from a '65 Imperial.  Neither one has this second, secondary butterfly, 
and no one on this list in the past knew why--and I'm still dying to 
know.  Obviously, these two carbs are designed to operate without it, 
while yours is designed to operate with it, so I'm guessing that you 
MIGHT have to retain it.  Either way, a very good question!
