FUEL FILTER
Clean or Replace Fuel Filter as follows:
1. Disconnect spark plug wire from spark plug. Remove
spark plug.
2. Drain fuel from tank before attempting to clean/replace
filter.
3. Remove hose clamp closest to gas tank.
4. Pull filter out from end of hose.
5. Filter may be washed with kerosene or similar solvent.
6. If filter is extremely dirty or torn, replace with new filter.
7. Reassemble with clean or new filter, and fill with clean,
fresh gasoline. Check for leaks prior to starting engine.
Transporting Engine
1. Never transport engine inside an enclosed space or
vehicle. Fuel or fuel vapors may ignite causing serious
injury or death.
2. If fuel is present in the fuel tank remove fuel or transport
with an open vehicle in an upright position.
3. If an enclosed vehicle must be used, remove fuel into an
approved red fuel container. DO NOT siphon by mouth.
4. Run engine or drain to use up the fuel in the carburetor
and fuel tank. Always run engine in a well ventilated
area.
5. Wipe away any spilled fuel from engine. Allow to dry.
Steps For Long-Term Storage
(30 days or more without use)
1. Add fuel stabilizer according to manufacturer’s
instructions.
2. Run engine for 10-15 minutes to ensure that the stabilizer
reaches the carburetor.
a) Start engine and run until engine runs itself out of any
residual fuel left in carburetor bowl and fuel lines. (It is
normal for the engine to run two to three minutes before
the fuel is completely out of system.)
3. Remove the remainder of the fuel from the fuel tank into
an approved fuel container.
4. Store engine in its upright position.
5. Remove all debris from engine.
6. Pull the starter handle slowly and return the handle to its
original position when resistance is felt. This operation
will prevent outside moisture from entering the
combustion chamber.
