Check and see if it is getting spark. I'm taking it it's cdi ignition? If so check and make sure you are getting juice down at the magneto. If so run the wires up to the coil and make sure everything is connected. If your not getting spark past the coil I would say it might not be grounding or the coil is bad. Also check the cdi box and make sure it is spitting juice out.
