Spark Arrestor

See Figure

Engines are equipped with a spark arrestor for

operational and environmental safety.
Every 100 hours of operation, remove and clean or

replace the spark arrestor

following the instructions

below.

WARNING

Hot Parts can cause severe burns.

Do not touch engine while operating

or just after stopping.

1. Remove the securing hardware (B) and the spark

arrestor

(A).

2. Clean the carbon deposits out of the screen using

a wire brush.

3. Check the spark arrestor (A). Replace if

damaged.

4. Reinstall the spark arrestor (A), securing with the

hardware (B) previously removed.

Clean Air Intake/Cooling Areas

To ensure proper cooling, make sure the recoil starter

screen, cooling fins, and other external surfaces of the

engine are kept clean at all times. Check daily.
Every 100 hours of operation (more often under

extremely dusty, dirty conditions), remove the blower

housing and other cooling shrouds. Clean the cooling

fins and external surfaces as necessary. Make sure the

cooling shrouds are reinstalled.
NOTE:

Operating the engine with a blocked grass

screen, dirty or plugged cooling fins, and/or

cooling shrouds removed, will cause engine

damage due to overheating.

Carburetor Troubleshooting and

Adjustments

See Figure

NOTE:

Carburetor adjustments should be made only

after the engine is at operating temperature.

The carburetor is designed to deliver the correct

fuel-to-air mixture to the engine under all operating

conditions. The idle mixture is set at the factory and

normally does not require adjustment.
If the engine is hard to start, runs roughly, or stalls

at low idle speed, it may be necessary to adjust or

service the carburetor. Engine must not exceed 3850

± 100 RPM if the high speed screw (A) is adjusted.
If engine troubles are experienced that appear to be

fuel system related, check the following areas before

adjusting the carburetor:

• Make sure the fuel tank is filled with clean,

fresh gasoline.

• Make sure that the fuel tank cap vent is not

blocked and that it is operating properly.

• Make sure the fuel shut-off valve is fully open.
• Make sure fuel shut-off valve strainer and

in-line fuel filter (if used) are clean and

unobstructed. Clean or replace as necessary.

• Make sure fuel is reaching the carburetor.

This includes checking the fuel lines and

components for restrictions or problems.

Replace as necessary.

• Make sure On/Off switch is functioning

properly.

• Make sure the air cleaner element is clean and

all air cleaner components are fastened securely.

If, after checking the items listed above, the engine is

hard to start, runs roughly, or stalls at low-idle speed,

it may be necessary to adjust or service the carburetor.
