      Ruben MoranJul 25, 2025
      If your MTD Tiller's engine won't start, there are several potential causes: * The spark plug wire might be disconnected, so connect it to the spark plug. * The fuel tank could be empty or contain stale fuel; in this case, fill the tank with clean, fresh gasoline. * The throttle control lever might not be in the correct starting position; move it to the start position (if equipped). * The choke might not be in the ON position; move the lever to ON. * There might be a blocked fuel line, so clean it. * The spark plug could be faulty; clean, adjust the gap, or replace it. * The engine might be flooded; wait a few minutes to restart, but do not prime (if equipped).
