For several years now, occasionally my starter on my 91 2.1 automatic would
not start.  A light tap with a hammer and all is well.  I'm getting ready to
head south after Christmas so I wanted to fix this before I'm stranded in a
rest area with a no start condition.  My challenge is the top bolt/crown
bolt on the starter that goes through the bell housing into the engine case.
Any words of advice before I break this thing off and I have a real problem.

Thanks Bob C
