John Deere mower with a Kawasaki fc420v-as10 has a Brocken magnet on the out side of the flywheel, motor had no spark, I replaced the magneto and module and disconnected the magneto ground wire and still no spark. Then I found the Brocken magnet where can I find a magnet and if I do find one what kind of epoxy two part glue do I use to attach it. (J B WELD?)
