If your lawn mower refuses to start, don’t panic. There are several common issues that can cause this problem, and many of them are easy to fix yourself. Here are some troubleshooting tips to get your mower up and running again.
Check the Spark Plug
A loose, dirty, or disconnected spark plug is a common culprit when a lawn mower won’t start. First, check that the spark plug wire is firmly connected. Then, remove the spark plug and inspect it. If it’s wet with fuel, that’s a good sign that the fuel system is working. However, if the plug is dry, it may indicate an issue with the fuel supply. Clean the plug with a wire brush or replace it if it’s heavily corroded.
Clean or Replace the Air Filter
A clogged or dirty air filter can restrict airflow and prevent the engine from starting. Locate the air filter, usually accessible by removing a cover, and either clean it thoroughly or replace it if it’s in poor condition.
Check the Fuel System
If the spark plug is in good condition, the issue may be with the fuel supply. First, check that there’s fresh fuel in the tank. Old or stale gas can cause starting problems. If the tank is full, try tapping the side of the carburetor to help the fuel flow. If that doesn’t work, you may need to replace the fuel filter.
