When you repaired the pull cord, you likely have shorted out the wire to the kill switch. So now the coil is grounded out. To test you can remove the kill wire from the coil and see if you have spark. If you do have spark, kill wire is grounded out. If no spark, the coil has failed!
Spark tester from auto supply is best, ***** ***** the spark plug attached to the wire, and ground it on the metal of the engine. A hose clamp and wire with alligator clip, with clamp holding test wire on the threads of the spark plug, makes good ground when you ground the alligator clip. Makes a real handy tool, just use a spare spark plug when testing.
