2.Remove the spark plugs and check the condition. Replace the spark plugs if worn or if reuse is questionable. See the “Service Schedule,” Section 6, for recommended inspection.

3.Check the spark plug gap using a wire feeler gauge. Adjust the gap to 1.07-1.17 mm (0.042- 0.046 inch) by carefully bending the ground elec- trode (Figure 10.4).
