Just a thought here, but if you made a pair of sheet metal covers to cover over the carb intake for the end carbs (bolt the carbs down over the covers), plug up the fuel lines to those carbs and disconnect the linkage to those carbs, you can use that manifold as a single manifold. Now you are running on just one carb and that may help you get your issue isolated a bit better.
