CARBURETOR ADJUSTMENT

Never make adjustments to the carburetor. The carburetor was set at the

factory to operate efficiently under most conditions. Only a qualified service

technician should adjust the carburetor if it is required.

MODIFYING THE CARBURETOR FOR HIGH ALTITUDES

At high altitude, the standard air-fuel mixture is 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 (1,524 m). Even with carburetor

modification, engine power will decrease about 3.5% for each 1,000 ft (305 m)

increase in altitude. The effect of altitude on engine power will be greater than

this is if no modification is made.

NOTICE! 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 (1,524 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.

CLEANING THE SEDIMENT CUP

CAUTION! Wear latex or rubber gloves when working on the sediment cup. The

cup may contain fuel that will cause skin irritation. Prolonged and repeated

exposure to fuel on skin may result in dry, cracked skin.

1. Switch the fuel valve to the OFF position.

2. Remove the fuel sediment cup, screw and o-ring.

3. Clean the sediment cup with a non-flammable solvent or detergent and

rinse. Allow to dry.

a. Some chemicals will damage the o-ring material. Check for

compatibility or replace the o-ring.

4. Reassemble the sediment cup and o-ring.

5. Switch the fuel valve to the ON position and check for leaks. Replace the

o-ring if the installation is correct, but fuel still leaks from the cup.

EMISSION CONTROL SYSTEM INFORMATION

The combustion process produces carbon monoxide, hydrocarbons and

nitrogen oxides. Controlling these emissions is important for personal and

environmental health.

8913188 14 HP 420cc OHV Gas Engine with Electric Start V1.0

16 For technical questions call 1-800-665-8685

REPLACEMENT PARTS

The emission control systems on the engine is designed, built and certified to

conform to Canadian emission regulations. Genuine parts are recommended

when servicing 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 the emission

control system.

It is the responsibility of the aftermarket part manufacturer to certify that the

part will not result in a failure of the engine to comply with emission

regulations.

SERVICE THE AIR FILTER

NOTICE! Operating the engine with a damaged or missing air filter will allow

dust and debris to enter the engine, causing rapid engine wear or scoring on

the engine pistons. Always ensure the air filter is in place.

A dirty air filter will restrict airflow to the carburetor, reducing the engine’s

performance. Clean the air filter more frequently than specified in the

maintenance schedule if the engine is used in dusty areas.

a. Remove the foam precleaner that is wrapped around the pleated

paper filter. Clean the dirty foam air filter element with warm water

and mild soap. Replace the water as necessary, until the water is no

longer dirty. Allow to dry.

b. Tap the pleated filter against a hard surface to dislodge dirt and dust.

Finer particulate matter may still remain lodged in the filter’s fibers.

c. Use clean compressed air to clean the pleated filter. Set the

compressor to a maximum of 30 PSI. Anything higher can damage

the filter. Hold the air nozzle inside the filter and direct the air stream

outward to blow the dirt and debris away from the outer surface.

NOTICE! Do not use compressed air with

chemicals to clean the air filter. The chemicals

could clog or dissolve the filter material.

d. Never attempt to brush the

accumulated dust and debris from

the filter. This will force the grime

into the fibers and plug the filter.

e. Reassemble the foam and paper

filter elements.

5. Reinstall the filter into the housing and

secure in place.

6. Install the air filter assembly onto the

carburetor and secure with screw.

REPLACING THE SPARK PLUG

NOTICE! Using an incorrect spark plug can cause engine damage. Only replace a

spark plug with a model recommended by the manufacturer.

The spark plug must be properly gapped and free of deposits for the best

performance. Check local bylaws to see if a resistor spark plug is required to

suppress ignition signals. Replace the included spark plug with a resistor spark

plug if required.

1. Remove any dirt from around the spark plug area.

CLEANING

WARNING! Only clean engine parts with a nonflammable solvent, unless

instructed otherwise. Keep all ignition sources away from fuel-related parts.

Fumes are flammable and may cause a burn injury or explosion if ignited.

NOTICE! Do not clean the engine’s exterior with a garden hose or pressure

washer. Water can enter the engine through the air filter or muffler opening

and damage the cylinder.

1. Allow engine 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.

STORAGE

DANGER! Fuel is very flammable. Use extreme care when handling or storing

fuel. An ignition source contacting the fumes or fuel can result in a fire or

explosion and cause fatal or serious injuries to you or a bystander.

When not in use for an extended period, apply a thin coat of lubricant to the

steel parts to avoid rust. Remove the lubricant before using the engine again.

Proper storage preparation is essential for keeping your engine in good

condition. The steps below will help keep rust and corrosion from impairing

your engine’s function and appearance. The engine will easier to start when

used again.

Take the following precautions if storing your engine for more than 30 days.

• Store in a clean dry area.

• Change the oil while the engine is still warm.

• Clean debris from the engine’s surface.

• Drain all fuel from the fuel tank into a proper receptacle for storage.

• Disconnect the spark plug lead and cover the end with insulating tape.

Place the lead where it cannot come in contact with the spark plug or the

equipment the engine is mounted on.

• Remove the spark plug. Place 1 teaspoon (5 ml) of oil into the spark plug

hole.

• Pull starter rope slowly 8 to 10 times to properly coat the cylinder bore

and piston for storage. Replace spark plug and tighten. Any residual oil

will burn off in subsequent starts. The muffler may emit white smoke.

• Store this engine in the horizontal position with the spark plug up. Do not

store or transport with the spark plug down. 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. Use a cover made from a breathable fabric to prevent rust and

corrosion.

5. Store with gasoline that does not contain ethanol or a similar alcohol-

based fuel additive. Fuel with alcohol-based additives may phase separate

into gasoline, alcohol and water when stored for more than a few weeks.

FUEL

IMPORTANT! Avoid fuel phase separation by using premium quality fuel of at

least 89 octane.

Gasoline with ethanol or alcohol-based additives may phase separate and

deteriorate in storage. Phase separated gasoline will cause hard starting and

leave gum deposits that clog the fuel system. Phase separated fuel will contain

water that will prevent the engine from working and may damage the engine

systems. You may need to service or replace the carburetor and other fuel

system components if that gasoline in your engine deteriorates during storage.

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 warm storage
