Carb question: bleedhole plug

Why do so many Linkerts for Indians have a 'tit' on the gallery plug that covers the idle bleed holes that H-D models do not?

Some of the small plugs that plug this same gallery at the manifold flange have tits too. Especially Scheblers.

Should I believe the tit makes a difference in fuelflow through the tiny bleeds?? The endplug makes no sense at all.(?)

Thanks in advance...

Might you be refering to what might not have been cut off during the machining of the plug during the screwmachine cutoff proccess? Didn't look at any yet but that's a possibilty. Did you notice if all the tits are all the same cup size?

No, these aren't just a tool mark; They are uniform extensions of the plug.
I have a j-peg, but am too confused by Sparkplug's site to post it.
