9. Check the spark plug gap before installing any

spark plug. See Figure 3-10. Attain a correct gap

when the feeler (or wire) passes between the spark

plug electrode. It should pass easily but with some

resistance or drag; otherwise adjust as necessary.

The correct gap is 0.8-0.9 mm (0.031-0.035 in.).

the threads or alter the electrode gap setting.

14. Check the spark plug wire connector in the boot for

accumulated dirt, grease, and other debris, and

clean as necessary.
