You didn't say if you are getting a spark at the plug or not. Are you getting a spark from the wire leading to the plug?

Got a trigger for my "83 80hp 4cyl. merc at outboardparts.com for $75.60. It'll cost you about about $15 to ship it. rebuilt my entire ignition system, stator, trigger,4 coils, rectifier and switchbox for a little over $500. shipping was free for orders over $200. were all Mercury or CDI parts.
