Which mill did you buy? If it's the Barley Crusher, I'd say leave it alone. Mine was set perfectly when I got it.
To actually answer your question, however, look for cracked husks (cracked, but in tact), whole kernals, and not too much flour.
On a side note, it's a trip to see you posting again. The place has grown and changed a bunch since you were last here. The last thing I remember was you slicing yourself open on a carboy.
Welcome back!!!
