Another possibility is the solenoid that makes the connections for the
high amp circuit and moves the starter pinion to engage with the
flywheel may stick because of dirt and old grease.  Mine has the same
symptoms and a few moderate whacks on the top of the starter has always
worked to free it up.  I will soon take it apart for cleaning,
inspection and lubrication.  Maybe at this point there is enough wear on
the pinion and erosion on the high amp contacts that replacement is the
best option.
