I'm having trouble with an old Sportsman 90 a friend gave me that he hasn't seen run in years. There wasn't a spark so I replaced the spark plug which did not fix the problem. I don' know much about repairing ATVs but I have a feeling it might have something to do with the CDI box because there are two open connections without wires attached. I've attached pictures for reference.
If this isn't the issue what else can I look for to asses the lack of spark.
