If you're talking about the B&S "Magnatron" ignition coil, the primary wire must grounded to stop the engine. So you need to find which terminal on the ign switch is closed (shorts to ground) when the key is in the "off" position.
Can easily do this with a VOM or DMM. Set the meter to the lowest resistance (ohms x 1) position. Remove the wiring connector from the switch. Now ground one meter probe to the the metal switch body, then with the key "off" test each switch terminal. The terminal with 0 ohms resistance will be where the magneto wire should be connected. (Tip: Make sure this terminal goes open with the key in "run" and "start"!)
No meter? A continuity tester will work. Or make a continuity tester from a flashlight battery battery and suitable small bulb.

It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package.
