79cc OHV Gas Engine V 4.0

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 (1,500 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 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 (1,500 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.

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 bypass 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.

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

V 4.0 79cc OHV Gas Engine

1. Hard starting or stalling after starting.

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.

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 engine

performance. If the engine is used in very dusty areas, clean the air

filter more frequently than specified in the maintenance schedule.

1. Remove the air cleaner’s outside cover. Be careful to prevent

dirt and debris from falling into the air cleaner assembly.

2. Remove the air filter from the air filter housing.

3. Clean the housing interior with warm soap and water.

Allow to dry before reassembly.

4. Inspect the air filter to see if you can clean it or if it should be

discarded. Discard if it is too dirty and replace with a new filter.

a. Clean dirty air filter with warm water and mild soap or a non-

flammable solvent. Replace the water as necessary, until the

water is no longer dirty. Dispose of the oil contaminated

water in accordance with your local by-laws.

Visit www.princessauto.com for more information

15

79cc OHV Gas Engine V 4.0

NOTICE! Do not use a flammable solvent to clean the foam

filter. The solvent may dissolve or clog the filter.

b. Allow air filter to dry.

c. Dip the filter into clean engine oil and squeeze out excess. The engine may

produce smoke when started for the first time after the filter is replaced.

This is excess oil from the filter and the effect is only temporary.

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.

2. Unclip the spark plug lead and remove the spark plug with a

spark plug wrench. This will have a rubber pad inside the

socket to protect the spark plug’s ceramic coating.

3. Inspect the spark plug. Replace it if damaged, badly fouled, the

sealing washer is in poor condition or the electrode is worn.

4. Check the gap with a spark plug gauge

as shown in Figure 6. If necessary,

reset the gap (See Specifications).

a. Correct the gap by carefully

bending the side electrode. Check

the gap after each adjustment.

5. Install the spark plug carefully by hand to avoid

cross threading. Fig. 6

6. Tighten the spark plug to the recommended torque until the gasket

is compressed. See Specifications for the correct torque rating.

7. Reconnect the spark plug lead to the spark plug.

engine parts. Keep all sources of ignition away from fuel related parts.

Fumes are flammable and may catch fire, causing a burn injury.

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 may 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 the debris, chaff or grass 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 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.

17

79cc OHV Gas Engine V 4.0

• 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 will burn off in

subsequent starts. This may result in white smoke emission from muffler.

• Store this engine in the 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. 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 with at least 89 octane.
