Storage Precautions
If your engine will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
ignition. Select a well ventilated storage area away from any
appliance that operates with a flame, such as a furnace, water
heater, or clothes dryer. Also avoid any area with a
spark-producing electric motor, or where power tools are
operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Keep the engine level in storage. Tilting can cause fuel or oil
leakage.
With the engine and exhaust system cool, cover the engine to
keep out dust. A hot engine and exhaust system can ignite or
melt some materials. Do not use a plastic sheet as a dust cover.
A nonporous cover will trap moisture around the engine,
promoting rust and corrosion.
Removal from Storage
Check your engine as described in the
CHECKS
section of this manual (see page 2).
If the fuel was drained during storage preparation, fill the tank
with fresh gasoline. If you keep a container of gasoline for
refueling, be sure it contains only fresh gasoline. Gasoline
oxidizes and deteriorates over time, causing hard starting.
If the cylinder was coated with oil during storage preparation,
the engine will smoke briefly at startup. This is normal.
TRANSPORTING
If the engine has been running, allow it to cool for at least 15
minutes before loading the engine-powered equipment on the
transport vehicle. A hot engine and exhaust system can burn
you and can ignite some materials.
TAKING CARE OF UNEXPECTED PROBLEMS
ENGINE WILL NOT START
Possible Cause
Choke open.
Engine switch OFF. (on the
equipment)
Out of fuel.
Bad fuel; engine stored without
treating or draining gasoline, or
refueled with bad gasoline.
Spark plug faulty, fouled, or
improperly gapped.
Spark plug wet with fuel
(flooded engine).
Fuel filter restricted, carburetor
malfunction, ignition
malfunction, valves stuck, etc.
ENGINE LACKS POWER
Possible Cause
Filter element restricted.
Bad fuel; engine stored without
treating or draining gasoline, or
refueled with bad gasoline.
Fuel filter restricted, carburetor
malfunction, ignition
malfunction, valves stuck, etc.
BEFORE OPERATION
Correction
Move lever to CLOSED position
unless the engine is warm.
Turn engine switch to ON
position.
Refuel (p. 4).
Drain fuel tank and carburetor
(p. 8). Refuel with fresh
gasoline (p. 4).
Gap or replace spark plug
(p. 6).
Allow the spark plug to dry.
After drying, install the spark
plug and start the engine (p. 2).
Take engine to your servicing
dealer, or refer to shop
manual.
Correction
Clean or replace filter element
(p. 5).
Drain fuel tank and carburetor
(p. 8). Refuel with fresh
gasoline (p. 4).
Take engine to your servicing
dealer, or refer to shop
manual.
TECHNICAL & CONSUMER INFORMATION
TECHNICAL INFORMATION
Serial Number Location
See Figure 16, page A-4.
Record the engine serial number [1], type [2] and purchase date
in the spaces below. You will need this information when
ordering parts and when making technical or warranty inquiries.
Engine serial number: __ __ __ __ — __ __ __ __ __ __ __
Engine type: ___ ___ ___ ___
Date Purchased: ______ / ______ / ______
Remote Control Linkage
See Figure 17, page A-4.
The throttle control lever is provided with a fitting for cable
attachment [1].
Remove the air cleaner cover (see page 5) for access to the
throttle lever and cable fitting.
Attach the throttle cable as shown in the illustration.
To adjust the throttle cable, follow the equipment
manufacturer's instructions.
Carburetor Modifications for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be
too rich. Performance will decrease, and fuel consumption will
increase. A very rich mixture will also foul the spark plug and
cause hard starting. Operation at an altitude that differs from
that at which this engine was certified, for extended periods of
time, may increase emissions.
High altitude performance can be improved by specific
modifications to the carburetor. If you always operate your
engine at altitudes above 1,500 meters, have your servicing
dealer perform this carburetor modification. This engine, when
operated at high altitude with the carburetor modifications for
high altitude use, will meet each emission standard throughout
its useful life.
Even with carburetor modification, engine horsepower will
decrease about 3.5% for each 300 meter increase in altitude. The
effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
When the carburetor has been modified for high altitude
operation, the air-fuel mixture will be too lean for low altitude
use. Operation at altitudes below 1,500 meters with a modified
carburetor may cause the engine to overheat and result in
serious engine damage. For use at low altitudes, have your
servicing dealer return the carburetor to original factory
specifications.
