    Disconnect the black kill lead wire from the engine to the tractor wire harness and check for spark again. This will eliminate all the safety switches etc, If you now have spark then it's time to start checking switches to find the bad one.

    If you still have no spark with the kill wire disconnected then the coil (Armature-Magneto) took a dump and needs replacing.
