CHECKING AND ADJUSTING VALVE LASH

CAUTION
Checking and adjusting valve lash
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) of the
compression stroke. Looking through the spark
plug hole, the piston should be at the top.
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 push rod and check for clearance (see Figure
20). See table below for valve lash specifications

7. Turn the adjusting nut to obtain the correct valve
lash. When the valve lash is correct, hold the
adjusting nut and tighten the jam nut to 106 in-lb
(12 N•m).
8. Recheck the valve lash after tightening the jam nut.
9. Perform this procedure for both the intake and
exhaust valves.
10. Install the rocker arm cover, gasket and spark plug.

BATTERY SERVICE

To ensure the battery remains charged, the generator
should be started every 2 to 3 months and run for
a minimum of 15 minutes or a charger should be
plugged into the generator and the generator should be
charged overnight. Plug the cord from the charger into
the charging port on the generator. Switch the engine
switch to the STOP position. Plug the charger into a
110/120-volt AC outlet.

Battery Replacement

1. Make sure Engine Switch if switched to STOP and
Battery Indicator light is off.
2. Remove the spark plug wire from spark plug.
3. Loosen and remove the bolts on the battery hold
down plate and swing the plate out.
