Depends on what lever ratio you run, valve body, front clutch clearance, number of springs in the front clutch, number of springs in the front servo. I find that 1 3/4 turns works good on mine. 15 springs in the clutch, 5 plate clutch at .070", inner and outer in the servo, 4.2 lever. It has over 100 low 9 second passes on it. Had it apart last week the band and drum look like they came out of the box.
