Default os carb hi-speed question.

pulled the hi-speed needle off of my OS21TM for cleaning. problem is that i didn't take note of WHICH WAY the "universal fuel nipple(where the fuel line attaches) went onto the brass needle, itself. seems that the fuel nipple has a shoulder that either goes on the top or(by flipping it around) on the bottom of the needle. this shoulder may provide some sort of a "trap" so that the fuel gets more effectively directed into the two ports on the needle........i called os support on this deal and they said that it doesnt matter. but, in that case.....why the shoulder ?? which brings me back around agian....which way does it go...????????????
