Default No white wire from coil

I just noticed that I have only blue and black wires coming from the coil. Where will I hook my kill switch to?
My kill switch is the one that is built into the throttle and has yellow and black.
Is my coil a reject? Should I send it back?

The white wire comes from the magneto (engine) not the CDI. From the Engine there is a blue, a black and a white. Connect the blue to the blue and the black to the black from the CDI then splice these with the wires from the kill switch. The white wire, unless you plan to try powering a light with it, should be capped and left unused. Don't be concerned with the different colors from your kill switch.
I'll attach a diagram (courtesy of Chris Hill at Home of the CH bicycle engine, CH80 Bicycle Engine Kits by Chris Hill, Motorized Bicycles, Bike Engine, Bike Motor, Bicycle Motor kit). (The grey circles where the wires meet indicate splices)

you dont need the kill switch, just let the clutch out slowly. many people have had problems with the kill switch. if you want one get a toggle switch and use it to break you cdi circut, open the black to black or blue to blue.

The wires from the kill switch go to the blue & black from mag...doesn't matter which one.

Mag 2 CDI...Blue 2 Blue..Black to Black. Or Green to Blue if you have a green wire from mag.

Never heard of no white wire But you should only need it if you want to run lights or something.

Toy,
It takes a big man to admit when he's wrong...but of course having never made a mistake in my whole life its a little hard to empathize...

you don't want to ground your white wire its not designed for that. The kill switch should be wired 1 into blue wire the other into the black. Blue and black are one circuit the white is a different one.

the white wire should be capped off and tapped shut.
