• Make sure the piston is at Top Dead Center (TDC)
of its compression stroke (both valves closed). To
get the piston at TDC, remove the intake screen at
the front of the engine to gain access to the flywheel
nut. Use a large socket and socket wrench to rotate
the nut and hence the engine. While watching the
piston through the spark plug hole. The piston
should move up and down. The piston is at TDC
when it is up as high as it can go.
• Loosen the rocker jam nut. Use an 10mm allen
wrench to turn the pivot ball stud while checking
clearance between the rocker arm and the valve
stem with a feeler gauge. Correct clearance is
0.002-0.004 inch (0.05-0.1 mm). See Figure 4.6.
Hold the rocker arm jam nut 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.
Start all four screws before tightening or it will not
be possible to get them in place. Make sure the
valve cover gasket is in place.
• Re-attach the spark plug wire to the spark plug.
• Repeat the process for the other cylinder.

COOLING SYSTEM

Air inlet and outlet openings in the generator com-
partment must be open and unobstructed for con-
tinued proper operation. This includes such obstruc-
tions as high grass, weeds, brush, leaves and snow.
Without sufficient cooling and ventilating air flow, the
engine/generator quickly overheats, which causes it
to quickly shut down. (See Figure 4.7 for vent loca-
tions.)

The exhaust from this product gets extremely
hot and remains hot after shutdown. High grass,
weeds, brush, leaves, etc. must remain clear of
the exhaust. Such materials may ignite and burn
from the heat of the exhaust system.

The maximum ambient temperature for the
generator is 48.9° C (104° F).

4.10 ATTENTION AFTER SUBMERSION

If the generator has been submerged in water, it MUST
NOT be started and operated. Following any submer-
sion in water, have a dealer thoroughly clean and dry
the generator.

4.11 CORROSION PROTECTION

Periodically wash and wax the enclosure using auto-
motive type products. Frequent washing is recom-
mended in salt water/coastal areas. Spray engine
linkages with a light oil such as WD-40.
