"Off the stop". Does this mean prop to be pulled back as in coarse pitch?
I've heard this before but if the blades are not tracking correctly or blade angles are not the same, it will cause an aerodynamic imbalance which cannot be 'fixed' by balancing. If blade tracing is out of limits balancing is generally not possible.
