HIGH ALTITUDE
For operation at altitudes of 2500 feet or more, close
the carburetor main jet adjustment slightly to main-
tain proper air-to-fuel ratio. Refer to the
Aa'jusfmenrs
section. Maximum power will be reduced about
4
percent for each
1000
feet increase in altitude.

PROTECTION FOR EXTENDED OUT-OF-
SERVICE PERIOD
Protect an engine that is to
beout-of-service for
more
than
30
days as follows:
1.
Run engine until thoroughly warmed up.
2.
Turn off fuel supply and run until engine stops
from lack of fuel.
3.
Drain oil from oil base while still warm. Attach a
warning to refill before operation.
4.
Remove each spark plug. Pour one ounce (two
tablespoons) of rust inhibitor (orSAE#50)
oil
into
cylinder. Crank engine over a few times. Leave at
top center position. Reinstall each spark plug.
5.
Service air cleaner.
6. Lubricate governor linkage. Protect against dust,
etc. by wrapping with a clean cloth.
7.
Plug exhaust outlet to prevent entrance of
moisture or dirt.
8.
Wipe entire unit clean. Coat parts likely to rust
with a light film of grease or oil.
9.
Provide a suitable cover for entire unit.

RETURNING THE SET TO OPERATION
1.
CHECK SERVICE IDENTIFICATION TAGS to
properly service the set.
2.
Uncover and remove all storage seals from unit.
Remove any dust, dirt, or foreign matter.
3.
CHECK fuel supply tanks for moisture ac-
cumulations (drain tanks if necessary). CHECK
lubricating oil for moisture or contamination
(drain if necessary). CHECK fuel line connec-
tions, all wiring connections, and exhaust line
connections.
4.
Service air cleaner (if used). Bleed fuel system (if
moisture or contamination are found
in
fuel,
replace filters and clean fuel pump sediment
bowl).
5.
Check tag on oil base and verify that oil viscosity
is still correct for existing ambient temperature.
6. Clean and check battery. Measurespecific gravity
