Portable Generator System
Figure 21 - Valve Clearance Adjustment
NOTE:
The rocker arm jam nut must be held in place as the pivot ball
stud is turned.
When valve clearance is correct, hold the pivot ball stud in place
with the allen wrench and tighten the rocker arm jam nut. Tighten
the jam nut to 174 in/lbs. torque. After tightening the jam nut,
recheck valve clearance to make sure it did not change.
Install new valve cover gasket.•
Re-attach the valve cover.•
NOTE:
Start all four screws before tightening or it will not be possible
to get all the screws in place. Make sure the valve cover gasket
is in place. Replace spark plug.
Re-attach the spark plug wire to the spark plug.•
3.7 LONG TERM STORAGE
It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose or tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during storage. Acidic
gas can damage the fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer, as follows:
Remove all gasoline from the fuel tank.•
DANGER
Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke.
Start and run engine until engine stops from lack of fuel.•
Allow the engine to cool, then drain oil from crankcase. Refill •
with recommended grade.
Remove spark plug and pour about 1/2 ounce (15 ml) of engine •
oil into the cylinder. Cover spark plug hole with rag. Pull the
recoil starter a couple times to lubricate the piston rings and
cylinder bore.
Avoid spray from spark plug hole when cranking
engine.
Install and tighten spark plug. Do not connect spark plug wire.•
Clean the generator's outer surfaces. Check that cooling air •
slots and openings on generator are open and unobstructed.
Store the unit in a clean, dry place.•
3.8 OTHER STORAGE TIPS
Do not store gasoline from one season to another.•
Replace the gasoline can if it starts to rust. Rust and/or dirt in •
the gasoline will cause problems with the carburetor and fuel
system.
If possible, store the unit indoors and cover it to give protection •
from dust and dirt. BE SURE TO EMPTY THE FUEL TANK.
If it is not practical to empty the fuel tank and the unit is to be •
stored for some time, use a commercially available fuel stabilizer
added to the gasoline to increase the life of the gasoline.
Cover the unit with a suitable protective cover that does not •
retain moisture.
DANGER
NEVER cover the generator while engine and
exhaust area are warm.
