2. Remove the spark plug with a 13/16-inch spark plug wrench.
3. Inspect the spark plug. Replace it if the electrodes are worn or if the insulator is cracked or chipped. Spark plug gap should
be set to 0.027 - 0.030 inches.
4. Install the spark plug carefully to avoid cross threading. Screw in spark plug by hand until it stops turning.
5. Tighten the spark plug with a 13/16-inch spark plug wrench. Tighten 1/4 turn after the spark plug seats.

Engine Oil Level Check
Check the engine oil level with the engine stopped and with the engine in a level position.
1. Remove either side mounted ller cap dipstick or high oil ll dipstick and wipe it clean.
2. Insert and remove the dipstick without screwing it into the ller neck. Check the oil level shown on the dipstick.
