cool before removing the spark plugs.
1. Clean the area around the base of the spark plug to
keep dirt and debris out of the engine.
2. Remove the spark plug and check its condition.
Replace the spark plug if it is worn or if its reuse is
questionable.
3. Check the spark plug gap using a wire feeler
gauge. See Figure 2-3 for the recommended spark
plug gap. Adjust the gap by carefully bending the
ground electrode. See Figure 2-4 and Figure 2-5.
