Marc,

I am reluctant to add anything new to the mix, but if the tach drops like a
rock to zero whenever the engine stutters while you are driving, it could be an
early symptom of a failing Hall Sender.  But first, set up the engine
properly as Bob has said.  An intermittent fault in the Hall Sender should not effect
the set up of the engine because whenever a Hall Sender queefs out either you
have spark or you don't.
