  If your White Outdoor Lawn Mower engine won't start, there are several potential reasons: * The PTO switch might be engaged, so disengage it. * The brake pedal may not be engaged, so engage it. * The spark plug wire could be disconnected, so connect it. * The throttle control lever might not be in the correct starting position, so move it to the FAST or START position. * The fuel tank might be empty or the fuel is stale, so fill it with clean, fresh gasoline (not over 30 days old). * The fuel line could be blocked, so clean it. * The spark plug might be faulty, so clean, adjust the gap, or replace it. * The engine might be flooded, so crank it with the throttle in the FAST position.
