NOTICE! Do not use compressed air with chemicals to clean the air
filter. The chemicals could clog or dissolve the filter material.
4.3 Never attempt to brush the accumulated dust and debris from the
filter. This will only force the grime into the fibers and plug the filter.
5. Reinstall the filter into the housing and secure in place.
6. Install the air filter assembly onto the carburetor and secure with screw.
REPLACING THE SPARK PLUG
NOTICE! Using an incorrect spark plug can cause engine damage.
Only replace a spark plug with a model recommended by the
manufacturer.
The spark plug must be properly gapped and free of deposits for the best
performance. Check local bylaws to see if a resistor spark plug is required to
suppress ignition signals. Replace the included spark plug with a resistor
spark plug if required.
1. Remove any dirt from around the spark plug area.
2. Unclip the spark plug lead and remove the spark plug with a spark plug
wrench. This will have a rubber pad inside the socket to protect the spark
plug’s ceramic coating.
3. Inspect the spark plug. Replace it if damaged, badly fouled, the sealing
washer is in poor condition or the electrode is worn.
4. Check the gap with a spark plug gauge as shown in Figure 8. If
necessary, reset the gap (See Specifications).
4.1 Correct the gap by carefully bending the
side electrode. Check the gap after
each adjustment.
5. Install the spark plug carefully by hand to
avoid cross threading.
6. Tighten the spark plug to the recommended
torque until the gasket is compressed. See
Specifications for the correct torque rating.
7. Reconnect the spark plug lead to the spark
plug.
