MAINTENANCE
DRAINING THE FLOAT BOWL
1. Remove the engine service cover.
2. Locate the drain hose extending from the bottom of the
carburetor float bowl.
Suitable Fuel Container
3. Place the loose end of the hose outside the generator
into an approved gasoline container to catch the drained
fuel.
4. Loosen the float bowl drain screw and allow the fuel to
drain. Tighten the float bowl drain screw.
5. Route the drain hose between the air cleaner housing
and the engine service cover. Install the engine service
cover.
DRAINING THE FUEL TANK
If storing the generator for longer than six months, drain
the fuel tank to prevent fuel separation, deterioration, and
deposits in the fuel system.
1. Unscrew the fuel tank cap. Remove the fuel screen filter.
2. Using a commercially available gasoline hand pump
(not included), siphon the gasoline from the fuel tank
into an approved gasoline container. DO NOT use an
electric pump.
3. Reinstall the fuel screen filter and the fuel tank cap.
4. Start the generator and allow it to run until the generator
engine stops.
5. Remove the spark plug.
6. Put a teaspoon of engine oil into the cylinder and
pull the recoil handle until resistance is felt. At this
position the piston is coming up on its compression
stroke and both valves are closed. Storing the engine
in this position will help prevent internal corrosion.
Return the recoil handle gently.
7. Reinstall the spark plug. Leave the spark plug boot
disconnected to prevent accidental starting.

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.
