GENERAL TROUBLESHOOTING
Feeler Gauge
■ Remove the spark plug cover. Remove the spark plug cap and the spark plug. Check and remove
the carbon deposit in the spark plug. The spark plug gap should be 0.65±0.05mm. Inspect the
electrodes for wear and deposits (Fig. 7).
■ Install the spark plug into the spark plug cap. Contact the negative electrode to the aluminum part
(Fig. 8).
■ Press the start button to check if the spark plug sparks.
■ Check the gap between the rotor and the ignition coil. Make sure the gap is between 0.012 and 0.015
in. (0.30-0.40 mm) as instructed in step 3 of the Ignition Coil Replacement section (Fig. 9).

Ignition Coil Replacement (See Figs. 10-11)
■ Remove the upper engine cover.
■ Remove the spark plug cover and the spark plug cap. Remove the 2 screws. Remove the ignition
coil and the washers (Fig. 10 - 11).

■ Replace with a new ignition coil.
■ To adjust the gap between the rotor and the ignition coil, first insert a feeler gauge of 0.014 in.
(0.35mm) between the rotor and the ignition coil, then rotate the rotor and align the magnetic pole
of the rotor with the ignition coil. Press down the ignition coil flush against the feeler gauge. Tighten
the screws to fix the ignition coil. Rotate the rotor counter-clockwise to remove the feeler gauge. Re-
check to ensure the gap is 0.012-0.015 in. (0.30-0.40 mm) (Fig. 9).
