thattreeguy - that's great news. Yes, a rubber restorer should do the trick, but in my case the rubber is still in great shape so just a dab of Iso was all that was needed.
Facelift3 - The manual states 3mm for the lateral weight, and that one doesn't have to change this setting when you upgrade the stock cartridge, which was the SV-27A (nice sounding cart btw, but alas only conical replacement styli are available). This is wrong as they should have said no need to change the 3mm setting IF the weight of your new cart is approx the same as the stock cart, around 5gr-6gr. I've tried quite a few carts on this deck and if their weight is considerably more (like 7+ grams) then the rod settings have got to be changed too.
You're right in thinking the lateral weight is not for adjusting azimuth, as that's something else entirely. If you're thinking of those two tiny screws on the underside of the arm near the pivot, then I strongly suggest you leave these well alone as things can get quite complicated
If the headshell is tilted to one side, a better idea is to slightly loosen that tiny screw that is located at the front of the arm (the one on the underside of the arm near the headshell) and very very carefully wiggle the headshell to it's correct position before tightening the screw again. The problem is that this only allows you a very minimal movement but, in some cases, it is just enough. I did this on a Pioneer PL12D I have and it corrected the slight tilt of the headshell. It is very fiddly though.
