Spark Plug Maintenance

The spark plug is essential for proper engine operation. The spark plug should be intact, free of deposits, and properly gapped. A bad or incorrectly installed spark plug can cause engine damage.

To inspect the spark plug:

1.Remove the spark plug by pulling on the spark plug cap.

2.Unscrew the spark plug from this generator by using the included spark plug wrench as illustrated in Figure 16.

3.Visually inspect the spark plug. If it is cracked and/or chipped, discard and install a new spark plug. A F6TC spark plug, such as NGK BPR5ES, is recommended.

4.Measure the spark plug electrode gap with a gauge. The gap should be 0.028-0.031in (0.7-0.8mm). (See Figure 17.)

5.If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base and then re-gap the spark plug.

6.Screw the spark plug back into place on this generator by using the included spark plug wrench.

7.Replace the spark plug cap.
