This was the simplest adjustment to this turntable ever, it looked more complicated than it was. Just as you said, clean piston, oil it. 10 minute repair, THANKS

Sounds simple enough, Thanks

I have (2) BG 4004 turntables and the pickup arm drops at different rates, one is perfect and the other is too fast. I adjusted the damper cylinder screw and it is turned all the way in. This did help but still too fast. Is there another adjustment that would help or is the cylinder bad? If it is bad can it be reworked?
