If the carb is properly adjusted and the AMC is not sticking ,manual leaning is not
needed.

In the Philippines we removed the AMCs and always leaned manually.  Here we adjust the AMCs rich to allow some manual leaning at normal cruise altitudes; ie 6,000-8,000'.  I've seen AMCs set too lean, resulting in overly lean mixtures at altitude.
