what do you need to know apart from what i have already said
Technician: Curtis B., Technician replied 2 months ago

With it not firing on starting aid, you likely don't have spark. Locate the small black wire at the kill switch on the throttle control, and check it for being grounded. If the wire is grounded, the spark will be killed.
