You know the little green slider on top of hte base of the arm? That's the anitskate. Try setting it to "0" when you adjust the counterweight. Get a test record then set the antiskate slider according to the test record instructions. Do this after you set the tracking force with the counterweight. Please see audioasylum's FAQ --> tonearm/cart setup pages, so you can get the idea of how all the setup dimensions work. If you know all this already, sorry.
