A lawnmower that starts and then immediately stops often has a fuel or air issue. Check the fuel level to ensure there's enough gas. Clean or replace the air filter to ensure proper airflow. Inspect the spark plug for damage or dirt, which can prevent a consistent spark. Finally, ensure the carburetor isn't clogged, as this can disrupt fuel flow. Regular maintenance and these checks can usually resolve the issue.
