On all B&O decks of this era, there are three springs that support the deck. I would suggest bending the back one up a little to see if that makes a difference. Most of the decks also allow a ltlle adustment laterally of these springs though I have not taken apart a 2200 to know the limit of this in these Beocenters. There is a releasing nut at the end of the spring that when loosened will allow a mm or so of play.
