    Did you check the spark plug ??? also has machine been sitting for a long time ??? Did it run before storing it for the winter, ?? Check the flywheel and pick ups may have rust and not making contact, claen off rust and try again for spark ....

    The only 100% sure way to verify if its good or bad is to replace with a known good unit. I've read a lot of manuals on a lot of engines. When it comes to electronic ignition there is no real good test.

    Kawasaki has a way to check the trigger using an ohms meter,but like the post before this one ,it is easier to try it with a Known good one

    If you hit something with the mower sometimes the keyway cracks. The flywheel will shift slightly, then no spark
