I've got a question.  On the pod filters, when you look inside the filter from the mounting side, about 5/8" in there is a narrowing, an inside flange if you will (at least there is on mine).  Upon taking measurements, it seems to me that this inside flange covers or at least significantly blocks air passage to the top vent in the venturi.  Here's a pic below to illustrate.  I know it's not a LS650 carb but the inlet design is similar.  The outer ring is the inside rubber that mounts and contacts the outside of the carb.  The inside ring is the ID of the inside flange.  Does this cause a problem?
