Second what Pogo said, I was going to mention that but assumed the switch AND wire had been removed which may well not be the case. Pogo, I may be wrong, but I think that black wire he shows is merely a ground connecting the main frame to the gas tank and not the old kill switch wire. Go ahead and undo the two screws holding the ignition to the frame and pull the ignition up off the shaft so that you can pull the black kill switch wire (which I believe you have your finger pointing to on the ignition) out from wherever it is lying around cut off and tape it off. If it does inexplicably run to that short jumper wire, remove it from the frame and tape/cap it. Then check for spark per Pogo's instructions. I have a spare capacitor I can mail you if the right one is hard to find on Ebay these days.
