Check your kill switch's ground and the switch itself, bypassing it if needful. This may not be yer prob, but those switches are crappy as all get out.

If the mag and the CDI are fine, this only leaves wiring and plug/plug wire - one of the things I love about these things is their simplicity

24 volts??? They only put out 6V!
Yeah, disconnect the kill switch wires & make sure the blue & white wires aren't grounding anywhere on the frame or engine.
Also, replace the sparkplug boot & wire!
