You can shim the tracking wheel to change its yaw alignment. A 0.005" shim should be thick enough, so a piece of aluminum can would be perfect.. Loosen the tracking wheel bolt and place the shim at a 3 or 9 o'clock position, then tighten the bolt. Experiment with shim location. Make sure the shim won't catch on the belt or wheel.
I need to do this when I run my KMG backwards.
