MAINTENANCE

CLEANING FUEL SEDIMENT CUP

See Figure 15.

The sediment cup prevents dirt and water that may have gotten into the fuel tank from entering the carburetor. If the engine has not been run for a long time, the sediment cup should be cleaned before use.

Turn the fuel valve to the off position.

Remove the sediment cup using a 10 mm wrench.

Remove the o-ring and filter.

Clean each of the parts in a high flash-point solvent.

Reinstall the filter, o-ring, and sediment cup. Tighten with 10 mm wrench to secure.

Return the fuel valve to the ON position and check for leaks.

SPARK PLUG MAINTENANCE

See Figure 16.

Fig. 15

The spark plug must be properly gapped and free of

 

deposits in order to ensure proper engine operation.

 

To check the spark plug:

SPARK PLUG

Remove the spark plug cap.

 

Clean any dirt from around the base of the spark

 

plug.

 

Remove the spark plug.

 

Inspect the spark plug for damage, and clean with

 

a wire brush before reinstalling. If the insulator

 

is cracked or chipped, the spark plug should be

 

replaced.

 

NOTE: If replacing, use the following recommended

 

spark plugs or equivalent: NGK, BP6ES.

 

Measure the plug gap with a feeler gauge. The correct gap is .028 - .031 in. Correct, if necessary, by

carefully bending the side electrode.

Fig. 16

Seat spark plug in position; thread in by hand to prevent cross-threading.

Tighten with spark plug wrench to compress washer. If spark plug is new, use 1/2 turn to compress washer appropriate amount. If reusing old spark plug, use 1/8 to 1/4 turn for proper washer compression.
