Jimbotac make sure that 1/16" behind the gullets ride the center of your wheels. Thats where you want the tention on the blade. then you want to make sure that the tail of the blade is 1/16" of the thrust bearing. By doing this you wont get any teeth drift from left or right. Next, you dont want to force your wood through. If your gullets dont maintain sawdust in them thats when you also get the chatter and teeth drift.
