– Using a 4 mm allen key remove the fi xing screw on the top of the red cover.
– Disconnect the spark plug wire lead and remove the spark plug with the key supplied.
Inspect the spark plug. Replace it if damaged or badly fouled, if the sealing washer is

correct the gap if necessary by carefully bending the side electrode.
The gap should be: 0.60-0.70 mm (0.024-0.028 in).
