There are multiple parts to the ignition:
1) the separate stator winding that powers the CDI
2) the pickup unit outside of the flywheel that triggers the CDI
3) the CDI itself
4) the coil
5) the spark plug
6) the wiring
I'd still bet it has to do with your CDI being grounded due to your switch cleaning work. You should be able to test the kill switch using a multimeter on continuity setting. It should read zero or very low ohms with the button pressed, then go to infinity when released.
Another test would be to figure out which CDI pin gets grounded to stop the motor. With the CDI disconnected, check continuity between that pin wire and ground. If there is conitinuity, your CDI is being grounded somehow.
You should be able to download a manual with a wiring diagram. That would help you figure out the CDI pins.
