Manual start models are equipped with a 6 Amp battery charging system. This power is rectified by diodes so that direct current voltage is utilized by the ignition system. Check that lanyard stop switch stops the engine. Follow the Maintenance Schedule recommendations to ensure that the engine is in peak operating condition. Not only does this allow the engine to develop full power, but equally important is the fact that the engine also will be operating in an rpm range that discourages damaging detonation.
