Check the engine for any visible issues or loose parts. Prime the fuel system by pressing the primer bulb until firm. Open the throttle slightly; too much can flood the engine. Set the choke if the engine is cold. Finally, pull the starter cord firmly. If it doesn't start after a few tries, check for common issues like spark plug or fuel line problems.
