Spark Arrestor
See Figure
19
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 aer 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 ns, and other external surfaces of the
engine are kept clean at all times. Check daily.
Every 100 hours of operation (more oen under
extremely dusty, dirty conditions), remove the blower
housing and other cooling shrouds. Clean the cooling
ns 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 ns, and/or
cooling shrouds removed, will cause engine
damage due to overheating.
Carburetor Troubleshooting and
Adjustments
See Figure
20
NOTE: Carburetor adjustments should be made only
aer 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 lled 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-o valve is fully open.
Make sure fuel shut-o valve strainer and
in-line fuel lter (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/O switch is functioning
properly.
Make sure the air cleaner element is clean and
all air cleaner components are fastened securely.
If, aer 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.
