Re: first and first Bb

The RH finger causes a pad to close on the upper joint, as well as one on the lower joint. The connection between is via the bridge. The cork on the bridge needs to be of a thickness to make the closures work. If the cork is too thin, the upper joint pad will not fully close. If the cork is too thick, the pad on the lower joint will not fully close, or will resist closure.

If the clarinet is assembled with the bridge parts misaligned, then usually that means not enough cork is coming into play, so the upper joint pad will not fully close. That would tend make the 1-1 Bb resistant or otherwise bad.

Note, that important cork can wear over time from use or careless assembly of the two joints. If the wear is gradual then the alignment tends to get increasingly picky. Eventually the cork needs to be replaced, or possibly the connection can be augmented with something like duct tape (which I blush to admit having done.)
