At the top, under Tools, you will find Alignment Protractors, that will help position your cartridge correctly in the headshell. I prefer Baerwald.
If that doesn't do the trick, try using a tracking force in the upper end of the cartridge's usable range.
For the anti-skate weight, a bit of light-test fishing monofilament is perfect, but a bit of thread will do.
Keep them spinning.
