4.6SPARK PLUGS

Reset the spark plug gaps or replace the spark plugs as necessary. See Section 4.13 for maintenance requirements.

1.Clean the area around the base of the spark plugs to keep dirt and debris out of the engine. Clean by scraping or washing using a wire brush and commercial solvent. Do not blast the spark plugs to clean.

2.Remove the spark plugs and check the condition. Replace the spark plugs if worn or if reuse is questionable. See Section 4.13 for recommended inspection.

3.Check the spark plug gap using a wire feeler gauge. Adjust the gap to 0.76 mm (0.030 inch) by carefully bending the ground electrode (Figure 4.5).
