Are you absolutely 100% sure your platter is perfectly level? How about where you mount your tonearm - is that perfectly level, too?
Check it, and recheck it. My table is on a wooden cabinet and "level" changes day-to-day (I tweak with pieces of card stock under the footers). No need to mess with AS until you confirm.
