Riding Lawn Mower Engine Cranks But Won't Start

Use promo code YOUTUBE to save 10% on searspartsdirect.com.

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.
