Hey, congrats on joining the RS-212 club! I've got the same problem as Marty with the cuing lever. I fiddled with it a bit, and I figure it's lost some damping fluid. There's hardly any solid info online about this arm. You probably have found this, but I'm attaching the manual (I got it from The Vinyl Engine). Pay close attention to section 4, recalibrating the ani-skate. Basically, when you've zero-balanced the arm with a chosen headshell/cartridge, the anti-skate spring should be relaxed. It's a little complicated (I still don't think mine is completely right), and may require reading several times. It's one of those 2-part adjustments where you get one thing right, then adjust the other thing, and then you have to go back and adjust the first thing again (et cetera, et cetera). It's fun!
Let me know if you have any questions (or answers...!).
