Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, have you checked?

  • if the ignition coil's green wire is tied to a good frame/engine ground; and
  • if the black/yellow wire from the CDI to the ignition coil has pulsating voltage when attempting to start.
