Help - Scroeder CB-9" tonearm - anti-skating setting issue


Hope someone can help here.
I have an old (original) version of the CB 9" arm which was developed for the Artemis TT.

I acquired it recently after building up the whole Artemis system.

The issue I am facing is that I am struggling to set the ant-skating correctly.
I reduced it so far that the screw is almost falling out, yet the tonearm swings outwards as I am trying to adjust the cartridge using a Dr Feickert rig. Correct VTA/VTF set, using a Fidelity Research FR-1 MK III retyped by Soundsmith.
I can listen to the first 2-3 recordings on the record (so at least I know everything is working fine) but then it starts jumping back (like there is a skip in the record). Tried several records, same result.

Manu al very basic and could not find other posts anywhere.
Thanks in advance!

recheck all your adjustments.  My arm tracks any record with/without any a/skate...or anything in between.  
Hi. I own a CB-L. I'm with stringreen, it tracks pretty much anything on any antiskate, setting but is awesome once dialled in.

Have you checked if the TT itself is level? 

Cheers

richardkrebs is right, check to make sure everything is level including whatever the tonearm is mounted too. Next, it is possible for the magnet to get stuck. Back the screw all the way out and tap the vertical shaft of the tonearm lightly just above the base with the arm in it's rest. Use a blank record if you have one. The arm should skate inwards at least a little. If not you should contact Frank here  http://www.schroeder-tonarme.de/impressum-1.html
