I've seen a couple misunderstandings in this thread.

A plug with a larger gap than specified will force the coil to produce greater
than normal voltage to fire.  Coil current in this case will generally decrease
unless the ignotion system can somehow force more energy into each pulse, which
a standard system will not do.  The coil will not run hot, but may fail due to
insulation breakdown.  This may be an intermittent failure, and may be
temperature sensitive due to interwinding distance changing.

A plug with a smaller gtap than normal will require less voltage than normal to
fire, and will draw greater current.  This will cause greater heating of the
coil.

Follow old, worn, high gap plugs with new, too tightly gapped plugs...
