Ditched the "Air Maze"...

[Lawrie]

I have looked at the B 2 carb on my bench, It would be fairly easy to alter the bowl air vent to a balanced style.(air cleaner is fitted)
My thoughts are to block it off at position U and drill a connecting hole through to the idle air supply that is connected to the carb just under the Venturi.
my question is, would it matter that when the choke is on it will be above the choke butterfly, should it be between the choke butterfly and the air cleaner.
