Hi Aceto,
Place the level all along the arc that the stylus will trace from the outer edge of the record to the inner groove. Once you have adjusted it to be perfectly level along that section, rotate the platter 180 degrees. Put the level along the same arc (from the outer groove to the inner groove where the stylus will pass as it plays the record). If it no longer reads level then you probably have something wrong with the platter.
Best,
Barry Kohan
