You might be able to get around this by flushing it with electronic componen t cleaner and then trying to work a drop of oil in there, but the only sure way it to take it apart and clean it by hand. As for the meter, you can't adjust a meter meant to be powered by mercury batteries so it will give you anything like reliably accurate readings with batteries with the wrong voltage. If you get it right at one end of the scale, it will be even farther off at the other end on the scale. You have to modify the meter. You do this by soldering in an appropriate shottkey diode in series with the battery compartment. This will allow you to use a silver oxide battery in the camera (but not an alkaline battery, which does not have a stable enough voltage).
