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.

MAINTENANCE

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.

6. If an adjustment is necessary, hold the rocker arm pivot
and loosen the pivot adjusting nut.
7. Turn the rocker arm pivot to obtain the specified
clearance. Hold the rocker arm pivot and re-tighten the
pivot adjusting nut to the specified torque.
Torque: 106 inch-pound (12 N•m)
8. Perform this procedure for the other valve.
9. Install the gasket, rocker arm cover, and spark plug.
