when he turns to GP Position and sees Tach Movement-- he knows- it will be an NO/CRANK/NO START

hope that helps some guru's out there
It is only a guess. It never happens to my CDI, touching wood.

I suspect it is something electrical loading the battery if the tach is bouncing around. May be a bad starter or weak battery. Try something simple first. Turn on the headlights and see whether it dims badly when starting. Try a new battery. Good luck.
