There is no doubt the nut should be tight and the lever should be free. I don't know the MX, but to me it sounds like there's a spacer missing under the nut. Perhaps it (the nut) came right off some time and the washer was lost? The solution is to make a washer. It probably needs to be only a few hundredths of a millimetre thick. Mylar sheet is good for this and easier to handle than metal shim material.
