Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, what is the burn color of the spark plug tip?
Additionally, have you checked the charging/battery voltage at:

  • idle to 2500 rpm;
  • rev / 3700.

This is an independent site and members of this online community provide information, repair tips, technical assistance as a form of paid Q & A service.
