The whole idea of using two of the carburetors that are sufficient to run an engine as a single defies logic. Insisting that "they work fine" that way doesn't wash. The laws of physics aren't "suggestions". There HAS to be a downside to over-carbureting an engine, even if the proponents of doing it refuse to admit it. If you're convinced you're going to break out in a terminal case of the hives if you don't have two carburetors on your engine, at least use some common sense and size them appropriately. The Jeep YF I mentioned before would be a very good starting point, as it's designed for an engine small enough that using two of them on a 235 won't create all the venturi velocity and lean mixture problems that running massively too big carbs can and will create. Of course, where dual carb enthusiasts are concerned, logic and reason has no place in the discussion.
