ASSEMBLY & INSTALLATION

VENT HOSE ASSEMBLY

The engine has a vent hose that attaches to the fuel tank's one-way

valve. The tank sits on top of the engine. Vapour form as the engine

warms the gasoline.

When the pressure inside the tank reaches a predetermined level,

the one-way valve releases the vapour into the vent hose, which is

connected to the air intake. The vapour and air are drawn into the

engine for combustion.

8996977 V-TWIN GAS ENGINE V1.1

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.

1. Unscrew the cap clips and press

down all four to free the air

cleaner lid.

2. Remove the air cleaner’s outside

cover. Do not allow dirt and debris

from to fall into the air cleaner

assembly.

3. Remove the foam filter from the

housing.

4. Remove the air filter from the air

filter housing.

5. Clean the housing interior with warm soap and water. Allow to dry

before reassembly.

6. Inspect the air filters 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 the dirty air filter by tapping it on a hard surface to

dislodge dirt and dust. Finer particulate matter may still remain

lodged in the filter’s fibers.

b. Use clean compressed air to clean the 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. Do not use compressed air with chemicals

to clean the air filter. The chemicals could clog or dissolve the

filter material.

Figure 5.

V1.1 V-TWIN GAS ENGINE 8996977

Page 17 Assistance available at www.princessauto.com or 1-800-665-8685

c. Never attempt to brush the accumulated dust and debris from

the filter. This will force the grime into the fibers and plug the

filter.

d. 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. Do not use a flammable solvent to

clean the foam filter. The solvent may dissolve or clog the

filter. Dispose of the oil contaminated water in accordance with

your local by-laws.

e. Allow air filter to dry.

7. Reinstall the filters into the housing and secure the lid with the cap

clips.

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.

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

recommended by the manufacturer.

V1.1 V-TWIN GAS ENGINE 8996977

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

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.

This engine has two spark plugs.

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.

8. Repeat for other 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. See

Specifications for the standard idle speed range.
