I've got an old 031AV that sees little use most years. It leaks oil from around the oil adjustment screw on the bottom of the case. Been getting progressively worse over the years, and can get pretty messy during the heat of the summer. I'm not sure how the oil adjustment screw is sealed against leakage. Is this a possible bad o-ring, gasket, or ???? Is there anything I can do that can fix this leak? Thanks in advance.
