72 MAINTENANCE Spark Plug Spark Plug Removal and Replacement 1. Use a spark plug wrench to remove the spark plug. 2. Inspect the spark plug each time you change the oil. The electrodes should be kept clean and free of carbon. The presence of carbon or excess oil will reduce proper engine performance. If possible, check the spark plug gap (area between electrodes) using a wire feeler gauge. 3. Reverse the procedure for spark plug installation. Torque to specification. See page 71. NOTE: It is advisable to replace the spark plug at least once a year to insure easy starting and good engine performance. |
