3. Clean the coke on the bottom of spark plug.
4. Check spark plug visually, if it has gap, then scrap it. If you use the spark plug again, clean
the spark plug with brush.
5. Use feeler gauge to measure the spark plug gap, the gap should be 0.5-0.75mm
（0.02-0.03in）, if necessary, bend a electrode to adjust it.
 The spark plug should be fixed, otherwise it becomes very hot and will damage the
generator.
6. Assemble the spark plug with hand and avoid screw dislocation.
7. After assembling a new spark plug with hand, tighten 1/2 circle and press the washer. If it is
an old spark plug, only need 1/8 or 1/4 circle.
