MAINTENANCE
FUEL VALVE MAINTENANCE
The fuel valve is equipped with a fuel sediment cup, screen,
and o-ring. The fuel valve 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. Turn the fuel valve to the OFF position.
3. Remove the sediment cup from the fuel valve. Remove
the o-ring and screen.
4. Wash the sediment cup, o-ring, and screen in a
nonflammable solvent. Dry thoroughly.
5. Place the screen and o-ring into the fuel valve. Install
the sediment cup and tighten securely.
6. Turn the fuel valve to the ON position and check for
leaks. Replace the fuel valve if there is any leakage.
7. Turn the fuel valve to the ON position and check for
leaks. Replace the fuel valve if there is any leakage.
VALVE CLEARANCE
Checking and adjusting valve clearance must be done
when the engine is cold.
1. Remove the rocker arm cover and carefully remove
the gasket. If the gasket is torn or damaged, it must be
replaced.
2. Remove the spark plug so the engine can be rotated
more easily.
3. Rotate the engine to top dead center (TDC) by pulling
the recoil handle slowly. Looking through the spark plug
hole, the piston should be at the top (both valves are
closed).
4. Both the rocker arms should be loose at TDC on the
compression stroke. If they are not, rotate the engine
360°.
5. Insert a feeler gauge between the rocker arm and the
valve stem to measure valve clearance.
