Troubleshooting a lawnmower that won't start
Why Does My Lawnmower Stall or Stop Running?
A stalling lawnmower is frustrating, but don’t panic! This article explores common causes and provides simple solutions to get your lawnmower running again.
Here are some of the most frequent culprits:
- Clogged Air Filter: A dirty air filter restricts airflow to the engine, potentially causing it to stall.
- Clogged Carburetor: The carburetor mixes fuel and air for the engine. Buildup can block fuel flow, leading to engine failure.
- Spark Plug Issues: A faulty, dirty, or improperly gapped spark plug can prevent the fuel mixture from igniting.
- Empty Fuel Tank: It sounds obvious, but an empty tank is often the reason a lawnmower stops running.
- Faulty Ignition Switch: A malfunctioning ignition switch can interrupt the electrical circuit and stall the engine.
