Fuel Filter Cup Cleaning

The fuel filter cup is a small well underneath the fuel valve. It helps to trap dirt and water that may be

in the fuel tank before it can enter the engine. To clean the fuel filter cup:

1. Turn the fuel valve to the “off” position.

2. Unscrew the fuel filter cup from the fuel valve using a wrench. Turn the valve toward you to

unscrew (see figure 30).

3. Clean the cup of all sediment using a rag or brush.

4. Reinstall the fuel filter cup.

Spark Plug Maintenance

The spark plug is important for proper engine operation. A good spark plug should be intact, free of

deposits, and properly gapped. To inspect the spark plug:

1. Pull on the spark plug cap to remove it.

2. Unscrew the spark plug from the generator using the spark plug wrench included with this

product (see figure 31).

3. Visually inspect the spark plug. If it is cracked or chipped, discard and replace with a new

spark plug.

4. Measure the plug gap with a gauge (see figure 32). The gap should be 0.7 -0.8mm (0.028-

0.031in).

5. If you are re-using the spark plug, use a wire brush to clean any dirt from around the spark plug

base and then re-gap the spark plug.

6. Screw the spark plug back into i ts place on the generator using the spark plug wrench. Place

back the spark plug cap.
