Re: no spark
remove the black wire with yellow stripe at the switchbox. try to start,understand that you cant shut the engine down,so disconnect the fuel line, and spray a few squirts of mixed fuel directly into the carbs, and try it. It it tries to start, something is grounding-out that black/yellow wire..Either the ignition switch,lanyard switch, mercury tilt switch,or short inside the wire harness itself,involving that black wire. <br />If still no fire, you'll need to get the switchbox and/or trigger tested.
