ok was riding the blaster all was running fine took my daugher for a slow put around yard and she died. i thought maybe fouled out the plug so put in new plug she ran for another 40 yard and died again now im getting no spark. this sound like a coil problem? cdi? or maybe just a bad switch? any help would be nice. We're kinda new to 2 strokes. seemed to be running fine up to that point.
