So there is the main jet passage with the needle in it, but the passage next to it with the pilot jet, there is another just in the same passage that needs to be unscrewed before I can get to it.
Should I take some pictures or something?

I have my main jet, and then beside it, is another "jet" with a 50 stamped on it. Once removed I can access the pilot jet.
So there is the main jet passage with the needle in it, but the passage next to it with the pilot jet, there is another just in the same passage that needs to be unscrewed before I can get to it.

I remember WG talking about that thing, I forget what it does but if I remember right he said you can leave it off with no ill effects.

It's a restricting jet that was put on some of the stock set ups in an attempt to further satisfy the emission minded people...definitely not needed, especially if you've got pods and other mods that require jetting her up.

I have taken some pictures of what is going on inside my carbs, hopefully this can shed some light on everything.
#1 in this picture is my main jet, #4 from what I understand is an emulsion tube.
Now, #2 Im pretty sure is my pilot jet, it has a 15 stamped on it. #3 though boggles my mind, I have no idea what it is. It has a 50 stamped on it.
#4 screws into the biggest hole in the center of the float bowl, and then #1 screws into that.
#2 screws in first in the smaller hole beside the one the main jet threads into. After I screw in #2, #3 threads into the same hole afterwards.
From what I am reading it seems that this can be omitted? Is this true?
I was thinking it may be time to rejet, get some smaller main jets, and maybe a 17.5 pilot jet.
