If engine fuel is to be stored for more than one season,
without gasoline stabilizer, it will gradually deteriorate. Also, if
it is stored in the engine’s gas tank without gasoline stabilizer it
is likely that your carburetor will have gum deposits, a clogged
fuel system and will VOID YOUR WARRANTY. Prepare the fuel for
extended storage.
Fuel System
To avoid stale fuel and carburetor problems, treat the fuel system
in the following manner:
NOTE: Always follow mix ratio found on the stabilizer container.
Failure to do so may result in equipment damage.
NOTE: It is NOT necessary to drain stabilized gas from carburetor.
Fuel Treatment
Add fuel stabilizer according to Manufacturer’s 1.
instructions.
Run engine at least 10 minutes after adding the stabilizer to 2.
allow it to reach the carburetor.
NEVER store the engine with the fuel in
the fuel tank inside a building with potential sources
of ignition such as a hot water heater, space heater,
clothes dryer, electric motor, etc.
NOTE: Instead of using a fuel preservative/stabilizer, you can
empty the fuel tank as described next in Extended Storage -
Draining the Fuel.
Extended Storage
Draining the Fuel
NOTE: Clean debris from the engine before draining fuel from
the carburetor.
NOTE: If you have prepared your fuel for short-term storage it
is NOT necessary to drain fuel that contains stabilizer from your
carburetor.
To avoid severe injury or death, DO
NOT pour fuel from engine or siphon fuel by mouth.
To prevent serious injury from fuel fires, empty fuel tank 1.
by running engine until it stops from lack of fuel. DO NOT
attempt to pour fuel from engine.
Run the engine while waiting until the remaining fuel is 2.
consumed.
NEVER leave the engine unattended
when it is running and NEVER run the engine in an
enclosed area.
Begin servicing the cylinder bore as per the following 3.
instructions.
Oil Cylinder Bore
When lubricating cylinder bore, fuel
may spray from the spark plug hole. To prevent
serious injury from fuel fires, follow these
instructions:
Carefully disconnect the spark plug wire and keep it away 1.
from the spark plug.
Keep the disconnected spark plug wire securely
away from the metal parts where arcing could
occur.
Carefully attach the spark plug wire to the
grounding post, if provided.
Disconnect the battery at the negative terminal first, if the
engine is equipped with a D.C. electric starter.
Turn off all the engine switches.
Remove the ignition key, if provided.
Remove the spark plug.2.
Squirt 1oz. (30ml) of clean engine oil into the spark plug 3.
hole.
Cover the spark plug hole with a rag to prevent fuel from 4.
spraying from the spark plug hole when the starter rope is
pulled.
NOTE: for engines equipped with a recoil starter, proceed
to Step 5. For engines equipped with electric starters,
proceed to Step 6.
Grasp the starter cord handle:5.
Pull the starter cord handle out slowly using a
full arm stroke.
Repeat once. This will distribute the oil
throughout the cylinder to prevent corrosion
during storage.
Proceed to Step 7.
Push starter button or turn ignition switch key to “START”: 6.
position. Immediately releases the starter button or turn
the ignition switch key to the “OFF” position. This will
distribute the oil throughout the cylinder to prevent
corrosion during storage.
Remove the rag from the spark plug hole.7.
Install the spark plug. 8.
Carefully disconnect the spark plug wire from the
grounding post, if provided.
Connect the spark plug wire plug wire to the spark plug.10.
Oil
Change the oil if NOT changed within the last 3 months. See
Checking and Changing the Oil earlier in this section.
