  • johnson 20 hp no fire

    I have a 73 20hp Johnson which was gave to me. Very clean motor. Throttle, shift linkage and tilt all work smooth. The kill button is gone. So the wires coming from the magneto, split from the coils to the kill switch are unplugged(since the kill switch is not there to plug in). I am getting no spark at the plugs. I took the hand crank and flywheel off to inspect the points and magneto. They look brand new, are in great condition. Gapped at .02. Everything looked new or very clean under the flywheel. How can I troubleshoot to see what is not letting my plugs spark? Is there a way i can check for spark before the coils? Even when there is no kill button? Also, all wires ohmed out.
    Eager to get this 20 running..
    Any help is appreciated,
    Thanks

    Well if the kill switch is gone the you should have plenty of spark. Verify that the points are not being grounded out. That will kill spark to the coils.
