I have a 1977 70hp Evinrude that is not getting spark on the top cylinder. I have changed the coils with new ones, changed the plugs, carbs were rebuilt and a link and sync done. Every once in awhile the top cylinder will fire and then it runs great, unfortunately this is not very frequently. Not sure where to look next and would appreciate any help I can get.

Could be pack or trigger. Go to CDI website and follow the trouble shooting guide on your style of engine.
