I have a 1993 merc.115. Will only start if throttle is advanced about half way up on to wide open. Cold or warm makes no difference. The spark is weak at neutral start posistion,only arcing between 1/8"to1/4" inch. Tried power pack didnt help, could stator or trigger be weak or bad.or should i be looking for another problem elsewhere. Thanks

I'm thinking stator but try disconnecting the rectifier to see if that fixes it first. That's the easy thing to do because the stator requires pulling the flywheel.
