Riding Lawn Mower Engine Cranks But Won’t Start



This video explains what to do when your riding lawn mower spins but won’t start. Once it’s spinning, the engine needs 3 things to run—fuel, spark and compression. We’ll help you find out which one of those elements is missing in your engine by showing you a quick starter fluid test that can rule out several issues. We’ll also show you how to check for and resolve fuel supply problems. We’ll then move on to checking the ignition system for problems by examining the spark plug, and the ignition coil. We’ll also check for a timing problem related to a damaged flywheel key before showing you how to do an engine compression test. Following these troubleshooting steps should help you get your riding lawn mower started so you can get back to mowing.

  1. Great video. Thanks. Our mower won't run. It's running with starter fluid but won't keep going. The back fire solenoid wasn't working when i tested it with a battery. I disabled it by cutting off the pin. The float bowl isn't filling up either way. It's a new fuel pump. I can't figure out why it won't work.
