It will just be the inertia setup gummed or rusted up. Remove the starter
and you will find the pinion moves on a spiral spline. It needs to be very
free to move on this, against the light spring. Thoroughly clean the spiral
spline both on the shaft and inside the pinion, using wire brush or a
suitable solvent depending on whether it is gummed or rusted up. You can
probably do an adequate job without taking it apart, although it is better
to take it apart to do it. DO NOT put any grease or oil of any kind on it,
or you will be repeating the job in the near future. Instead, rub the
surfaces with powdered graphite.
The problem will be made worse by a sluggish starter, whether caused by the
starter itself or poor connections or battery. There is a slight chance
that the problem is damaged teeth on the flywheel or pinion, but this
should be obvious when you have the starter off, and in any case usually
make themselves kown by horrible noises rather than just spinning.
