necessary.

WINTER ENGINE - AIR FILTER

A winter engine does not have an air filter element, as the dry winter air

is unlikely to carry dust or debris.

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.

V1.0 GAS ENGINE FOR SNOWBLOWER 8871626

Page 15 Assistance available at www.princessauto.com or 1-800-665-8685

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. 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. FIGURE 5.

ADJUSTING THE ENGINE IDLE SETTING

NOTICE! The engine speed is set by the factory. Increasing

the speed too much can damage the engine. Too low a

speed will reduce the engine’s efficiency. Have a qualified

technician adjust the engine speed if necessary.

The engine’s idling speed is adjustable by turning the governor arm

screw to lower or increase the engine output (RPMs).

1. Remove the shroud and locate the governor arm screw.

2. Start the engine and wait for it to idle.

3. Tighten the screw to increase the engine speed. Loosen to reduce

speed.

4. Shut the engine off and allow to cool.

EMISSION CONTROL SYSTEM

INFORMATION

The combustion process produces carbon monoxide, hydrocarbons

and nitrogen oxides. Controlling these emissions is 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

system.

2. Do not alter or bypass the governor linkage or a speed-adjusting

mechanism that force the engine to operate outside its design

specifications.

PROBLEMS THAT MAY AFFECT EMISSIONS

Have your engine inspected and repaired by a qualified technician if

you are aware of any of the following symptoms.

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 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.

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. If

necessary, reset the gap (See Specifications).

5. Correct the gap by carefully bending the side

electrode. Check the gap after each adjustment.

6. Install the spark plug by hand, to avoid cross

threading, until the gasket is compressed. Tighten

an additional 1/2 to 1/3 turn more with a spark plug

wrench or to the recommended torque if listed in

the Specifications.

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

ADJUSTING THE ENGINE IDLE SETTING

NOTICE! The engine speed is set by the factory. Increasing

the speed too much can damage the engine. Too low a

speed will reduce the engine’s efficiency. Have a qualified

technician adjust the engine speed if necessary.

1. Start the engine and wait for it to idle.

2. The idle screw is above the fuel sediment cup. Tighten the screw

to increase the engine speed. Loosen to reduce speed. The

standard idle speed is 1,800 ± 150 RPM.

3. Shut the engine off and allow to cool.

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 muffler opening and damage the cylinder.

1. Allow engine to cool for at least half an hour before cleaning.

2. Remove debris from all cooling fins, air intakes and exhaust ports.

3. Clean all exterior surfaces.

4. Touch up any damaged paint.

5. Coat 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.

V1.0 GAS ENGINE FOR SNOWBLOWER 8871626

Page 19 Assistance available at www.princessauto.com or 1-800-665-8685

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.

FUEL STORAGE

Gasoline will oxidize and deteriorate in storage. Deteriorated gasoline

makes it harder to start the engine and leaves gum deposits that clog

the fuel system. If that gasoline in your engine deteriorates during

storage, you may need to service or replace the carburetor and other

fuel system components.

The length of time that gasoline can be left in your fuel tank and
