I think he means the black stuff on the thing with the 4 holes. Looks like a slug took a dump in there.

That is a tiny bit of rubber that was attached to the rubber in the centre of the plastic disc.
The disk holds a rubber diaphragm beneath it and the tiny bit of detached rubber is part of that diaphragm.
The loose bit is a sort of nipple. The bit is drawn through the disc and locks in place.

I Think the tiny valve just keeps dirt out of the inner workings of the larger internal diaphragm.
My petcock still works fine in spite of that part of mine barely hanging on.
Reassemble and see if it all works. I think it will be fine.

Well in the case of the plugs you would need new ones.
Carb o-rings should always be replaced when refreshing an old set of carbs.
They are cheap from Robert Barr a fellow site member.
