Spark Plug Service
In order to service the spark plug, you will need a spark plug wrench (commercially available).
Recommended spark plugs: NHSP LD F7TC or NGKBPRGES but we recommend our OEM spark
plug. To ensure proper engine operation, the spark plug must be properly gapped and free of
deposits.
1. Remove the spark plug cap.
2. Clean any dirt from around the spark plug base.
3. Use a spark plug wrench to remove the spark plug.
4. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. Clean the spark
plugwith a wirebrushifitistobereused.
5. Measure the plug gap with a feeler gauge.
(Correct as necessary by carefully bending the side electrode.)
The gap should be : 0.70-0.80 mm (0.028-0.031in)
6. Check that the spark plug washer is in good condition.

Fuel Sediment Cup Cleaning
The sediment cup prevents dirt or water which may be in the fuel tank from entering the carburetor.
If the engine has not been run for a long time, the sediment cup should be cleaned.

2. Clean the sediment cup, and O-ring, in nonflammable or high flash point solvent.
3. Reinstall O-ring, and sediment cup.
