Weird Carb Needle Jets.

[Crazy Damian]

Tore down my carbs and I'm cleaning everything, Have a lot of new jets on the way to me from Jets-r-us.
Ran into a weird issue with the Needle Jets, The one that goes down the middle of that carb that the Main jet threads into.
I didn;t mark them when I pulled them so I don't know which carb they go back in, and I have 2 different types.
2 of them have 4 holes on each of the 4 sides.
2 of them have 3 holes on 2 sides and 2 holes on the other 2 sides.
I read the manual, did an in depth search on here and cannot find any info on this.
Anyone have any ideas?

Those are the emultion tubes. The ones with less air bleed holes go in the center two carbs. The ones with more holes go in carbs 1 and 4.

Awesome!

Awesome, fast and easy I like it.
Another question, whats the reason for using the 2 different in the middle 2 cylinders? Why didn't they just go with the same all the way across?

Little bit richer in the center 2 to stay a little cooler.
