Edelbrock 1406 secondary venturi cluster

In regards to the secondary bog, I am not concerned much about that. I am curious of the fact the well tubes have tiny orifices compared to the older Carter well tubes. My question is does this restrict the jetting on the secondary circuit.

I think it is simply a different design. I usually have an AFB style carburetor, but I apologize. Right now I do not. I am pretty sure on the one with the large orifice opening, you will find that it has a restrictor inside somewhere between the large opening and where it enters the booster.
