EMISSION CONTROL SYSTEM INFORMATION
The combustion process produces carbon monoxide, hydrocarbons, and oxides of nitrogen. Control of
these emissions is very important for personal and environmental health.
The following instructions must be followed in order to keep the emissions from your engine within
Canadian emission standards.
1. Do not remove or alter any part of the intake, fuel, or exhaust systems.
2. Do not alter or defeat the governor linkage or speed-adjusting mechanism to cause the engine
to operate outside its design specifications.
PROBLEMS THAT MAY AFFECT EMISSIONS
If you are aware of any of the following symptoms, have your engine inspected and repaired
by a qualified technician.
1. Hard starting after stalling.
2. Rough idle.
3. Misfiring or backfiring under load.
4. Afterburning (backfiring)
5. Black exhaust smoke or high fuel consumption
REPLACEMENT PARTS
The emission control systems on your engine were designed, built, and certified to conform to Canadian
emission regulations. The use of genuine parts is recommended whenever maintenance is done to the
engine. Genuine replacement parts are manufactured to the same standards as the original parts. Using
replacement parts that are not of the original design and quality may impair the effectiveness of your
emission control system.
It is the responsibility of the manufacturer of an aftermarket part to certify that use of the part will not
result in a failure of the engine to comply with emission regulations.

MODIFYING CARBURETOR FOR HIGH ALTITUDES
At high altitude, the standard air-fuel mixture will be too rich, causing increased fuel consumption and
decreased performance. A rich mixture will also foul the spark plug and cause hard starting.
A qualified technician can improve high altitude performance with certain modifications. Have your
carburetor modified if the engine will routinely be operated at altitudes above 5,000 ft (1,500 m). Even
with carburetor modification, engine power will decrease about 3.5% for each 1,000 ft (300 m) increase
in altitude. The effect of altitude on power will be greater than this is if no modification is made.
CAUTION! 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 5,000 ft (1,500 m) may cause the engine
to overheat and result in serious engine damage. When using this engine at low altitudes, have a
qualified technician return the carburetor to original factory specifications.
STORAGE
WARNING! Keep the engine away from sources of open flame such as the pilot light of a furnace,
stove, water heater or other appliances when storing with fuel in the tank, as an ignition source can
ignite gasoline vapors.
WARNING! Transport the Engine with an empty fuel tank or with the fuel shut-off valve secured in the
OFF position.
Proper storage preparation is essential for keeping your engine in good condition. The steps below will
help to keep rust and corrosion from impairing your engine’s function and appearance, and will make the
engine easier to start when used again.
The following precautions should be taken if storing your engine for a period exceeding 30 days, or for
seasonal storage.
1. Store in a clean dry area.
2. Change the oil while the engine is still warm.
3. Clean the debris, chaff or grass from the engine’s surface.
4. Drain all fuel from the fuel tank into a proper receptacle for storage.
5. Remove the spark plug. Place 1 teaspoon or 5 ml of oil into the spark plug hole.
6. Pull starter rope slowly 8-10 times to properly coat the cylinder bore and piston for storage.
Replace spark plug and tighten. Any residual oil may burn off in subsequent starts. This may
result in white smoke emission from muffler.
7. Store this engine in horizontal position with the spark plug up. Do not store or transport with
the spark plug down.
Note: Storing or transporting with the spark plug down will result in hard starting and/or engine smoking.

STORING ENGINE WITH FUEL
1. If your engine will be stored with gasoline in the fuel tank and carburetor, it is important to
reduce the hazard of gasoline vapour ignition.
a. Select a well-ventilated storage area away from any appliance that operates with a flame,
such as a furnace, water heater, or clothes dryer.
b. Avoid any area with a spark-producing electric motor.
c. Avoid any area where power tools are operated.
2. If possible, avoid storage areas with high humidity, as this promotes rust and corrosion.
3. Keep the engine level in storage. Tilting can cause fuel or oil leakage.
4. Cover the engine once the engine and exhaust system are cool. Some materials can ignite or
melt if the engine and/or exhaust system is hot. Do not use sheet plastic as a dust cover.
a. Do not use a nonporous cover, as this will trap moisture around the engine and promote
rust and corrosion
TRANSPORTING THE ENGINE
1. Keep the engine level when transporting to reduce the possibility of fuel leakage.
2. Turn the fuel valve to the OFF position.
REMOVAL FROM STORAGE
1. Check the engine as describe in the section Before Operation.
2. If the fuel was drained during storage preparation, fill the tank with fresh gasoline.
a. If you keep a container of gasoline for refuelling, ensure that it contains
only fresh gasoline.
b. Gasoline will oxidize and deteriorate over time, causing hard starting.
3. If the cylinder was coated with oil during storage preparation, the engine will smoke briefly at
start up. This is normal.
CLEANING
CAUTION! Do not use a garden hose or pressure washer to clean the engine, as this may cause water
to enter the cylinder and cause damage.
1. If the engine has been running, allow it to cool for at least half an hour before cleaning.
2. Clean all exterior surfaces.
3. Touch up any damaged paint.
4. Coat other areas that may rust with a light film of oil.

FUEL
Gasoline will oxidize and deteriorate in storage. Deteriorated gasoline will cause hard starting, and it
leaves gum deposits that clog the fuel system. If that gasoline in your engine deteriorates during storage,
you may need to have the carburetor and other fuel system components serviced or replaced.
The length of time that gasoline can be left in your fuel tank and carburetor without causing functional
problems will vary with factors such as gasoline blend, storage temperatures, and the amount of fuel in
the tank. The air in a partially filled fuel tank will promote fuel deterioration, as will very warm storage
temperatures. Fuel problems may occur in a few months or sooner if the gasoline was not fresh when the
tank was filled.
Adding a gasoline stabilizer that is formulated for this purpose can extend fuel storage life. Deterioration
problems can also be avoided by draining the fuel tank and carburetor prior to storage.
ADDING A GASOLINE STABILIZER
1. Fill the fuel tank with fresh gasoline. If the tank is only partially filled, air in the tank will promote
fuel deterioration during storage.
2. Add gasoline stabilizer. Ensure that the instructions for that product are followed.
3. Run the engine outdoors for 10 minutes to ensure that treated gasoline has replaced the
untreated gasoline in the carburetor.
4. Stop the engine.
DISPOSING OF ENGINE
If your engine has become damaged beyond repair, do not throw it out. Bring it to the
appropriate recycling facility.
