If your mower isn’t starting, there are a few things you’ll want to check. You can use a spark plug tester to make sure your spark plug isn’t worn out. See how to use a multimeter to see if the stop wire is shorting to the engine. Then, you’ll want to check the air gap between the ignition coil and the flywheel. Lastly, you’ll want to check your flywheel key to make sure it isn’t broken or damaged. This video will walk you through the process so you can get to the root of your problem and fix it.
