Hi. Assuming that both the tracking weight and bias are correct, arm drift ( to outer edge of the record ) can occur if the cueing platform and underside of the tonearm which contacts it is greasy or dirty, the outward pull of the bias causes this. Simply use a cotton bud and a bit of isopropyl alcohol and clean the underside of the arm and the rubber/plastic top surface of the cueing platform. That usually stops it.
