That vent tube is used to sense the outside the pressure for the float bowl.

If your air cleaner is dirty that will change the sensed pressure. Of course it also changes the pressure in the venturi so maybe it is a wash...

There are metal "cups" that can be placed under the carbs to catch the fuel drips.
