IgnitionIgnition SystemThese models are equipped with an electronic ignitionsystem. One of the characteristics of this system is thatthe spark across the spark plug electrode gap has ahigher energy and shorter burning time (arc durationtime). When viewing the spark on a properly functioningignition system, the spark will appear to be weakercompared to breaker point ignition systems due to theshorter arc duration time.Spark PlugChampion RCJ7Y and NGK BPMR6A are the only sparkplugs that should be used. The spark plug should beremoved, cleaned and inspected at least once a week.The spark plug electrode gap should be 0.5 mm(0.020 in.).If the electrodes are worn, install a new, properly gappedspark plug.Checking for SparkRemove the spark plug. Move the ignition stop switch tothe “ON” position.
