Holley 4150 Rebuild question

So I decided to rebuild the carb that came on my engine, I'll probably get a new one thats a little more hi-po anyway and keep it as a spare. When I was taking off the metering block where the powervalve is located i noticed a piece on the cardboard i was working on that i didn't remove myself.
Can someone tell me where this goes and/or what its called, I'll post a picture, it looks like the lead of a pencil tip. Its too small to acurately pick it out in the parts blow up.

Pic is a red box for me! Did you take the squirters out? Under them is a needle that goes in first.

I cant see a picture either. Just a red x. Got me curious though. I built carburetors for several years for barry grant but nothing is coming to mind. The needle under the squirter is brass. Atleast every one I have ever seen. All you removed was the bowl and metering block?

It almost does resemble a viton tip(after i looked up pictures for it haha) But there is a possibility it came from somewhere else i suppose. It wouldn't be too likely but it is possible. I'm ordering a new carb anyway but i would like to be more positive it works. Sorry the picture didn't come up maybe its because i used a link from my email.
Thanks for your interest in helping
