Autolite 4100 overflowing

The autolite 4100 that I just rebuilt is overflowing. I am doing some tests tonight to see why the needle isn't seating, but I have a question.

I was looking at the thread and page on the Mrs American 3.14... carb rebuild and noticed a distinct difference in the floats.

A. His are brass, mine are not.
B. His has a little spring on them, mine did not. Did non-brass floats have this spring too? It wasn't there on either float when I disassembled, but is it supposed to be? I wonder if this is why the needed doesn't get enough pressure to close. But, the question would then be, how did it work before?

An illustration is below, look at #13 for the spring I am talking about.
