A few thoughts:
Buy something like this so you can really see if your stylus is clean

The recommendation for test records is a plus so you can check the tracking and improve the alignment
What alignment are you using? Some are less favorable to inner groves tracking
The cartridge may not be a good match for your arm, but even so is should track better than you indicate, so I would increase the tracking force to 2 grams and try it
