SPARK PLUG MAINTENANCE

Inspect and clean the spark plug after every 100 hours of
use or six months. Replace the spark plug after 300 hours
of use or every year.
ALWAYS use the Westinghouse OEM or compatible
non-resistor-type spark plug. Use of resistor-type spark
plug can result in rough idling, misfire, or may prevent
the engine from starting.
1. Place the generator on a level surface and allow the
engine to cool.
2. Remove the spark plug boot by firmly pulling the spark
boot directly away from the engine.
3. Clean the area around the spark plug.
4. Remove the spark plug with the included spark plug
socket wrench.
NEVER apply any side load or move the spark plug
laterally when removing the spark plug.
5. Inspect the spark plug. Replace if electrodes are
pitted, burned, or the insulator is cracked. Only use a
recommended replacement plug.
6. Measure the spark plug electrode gap with a wire-type
feeler gauge. If necessary, correct the gap by carefully
bending the side electrode.
Spark plug gap: 0.024 – 0.032 in. (0.60 – 0.80 mm)
7. Carefully install the spark plug finger tight, then tighten
as additional 3/8 to 1/2 turn with the spark plug wrench.
8. Attach the spark plug boot.

FUEL VALVE MAINTENANCE

The fuel valve is equipped with an inline fuel filter. The
fuel valve filter does not require servicing if the unit
is properly maintained with fresh, clean fuel. If fuel-
related troubleshooting is required, perform fuel valve
maintenance.
1. Allow the generator to cool completely.
2. Place an appropriate gasoline container under the
carburetor drain bolt to catch the drained fuel.
3. Remove the drain bolt on the bottom of the carburetor
and allow the fuel tank to drain completely. Install and
tighten the drain bolt securely.
4. Remove the fuel line from the fuel valve. Be prepared to
capture the remaining fuel from the fuel line.
5. Loosen the retaining bolt. Unscrew and remove the fuel
valve from the fuel tank. Be prepared to capture any
remaining fuel from the fuel tank.
6. Open the fuel valve. Use compressed air to clean the
fuel filter and the fuel passage from the fuel line side of
the passage.
7. Install and tighten the fuel valve until it has a few threads
remaining and is facing outward.
8. Hold it in place and tighten the retaining bolt. DO NOT
overtighten.
9. Replace the fuel line and secure with the clamp.
