STORAGE (IF THE ENGINE IS TO BE UNUSED FOR 30 DAYS OR MORE)
CAUTION: NEVER STORE THE ENGINE WITH FUEL IN THE TANK INDOORS OR IN ENCLOSED,
POORLY VENTILATED AREAS, WHERE FUEL FUMES MAY REACH AN OPEN FLAME, SPARK
OR PILOT LIGHT AS ON A FURNACE, WATER HEATER, CLOTHES DRYER OR OTHER GAS
APPLIANCE.
Gasoline can become stale in less than 30 days and form deposits that can impede proper fuel flow and
engine operation. To prevent deposits from forming, all gasoline must be removed from the fuel tank and
the carburetor. An acceptable alternative to removing all gasoline, is by adding Tecumseh's fuel stabilizer,
part number 730245, to the gasoline. Fuel stabilizer is added to the fuel tank or storage container. Always
follow the mix ratio found on the stabilizer container. Run the engine at least 10 minutes after adding
the stabilizer to allow it to reach the carburetor.
Draining the Fuel System
CAUTION: DRAIN THE FUEL INTO AN APPROVED CONTAINER OUTDOORS, AND AWAY FROM
ANY OPEN FLAME OR COMBUSTION SOURCE. BE SURE THE ENGINE IS COOL.
1. Remove all gasoline from the fuel tank by running the engine until the engine stops, or by draining the
fuel tank by removing the fuel line at the carburetor or fuel tank. Be careful not to damage the fuel line,
fittings, or fuel tank.
2. Drain the carburetor by pressing upward on bowl drain (if equipped) which is located on the bottom
of the carburetor bowl. On carburetors without a bowl drain, the carburetor may be drained by loosening
the bowl nut on the bottom carburetor one full turn. Allow to completely drain and retighten the bowl
nut being careful not to damage the bowl gasket when tightening.
3. If "Gasohol" has been used, complete the above procedure and then put one half pint of unleaded
gasoline into the fuel tank and repeat the above procedure. If Gasohol is allowed to remain in the fuel
system during storage, the alcohol content can cause rubber gaskets and seals to deteriorate.
Change Oil: If the oil has not been changed recently, this is a good time to do it. See "Oil Change Procedure"
on page 3.
Oil Cylinder Bore
1. Disconnect the spark plug wire and ground the spark plug wire to the engine. Remove the spark plug
and put a 1/2 ounce (15 ml.) of clean engine oil into spark plug hole.
2. Cover the spark plug hole with a shop towel.
3. Crank the engine over, slowly, several times.
4. Install the spark plug and connect the spark plug wire.
Clean Engine: Remove the blower housing and clean all dirt, grass or debris from the intake screen, head,
cylinder cooling fins, carburetor, governor levers and linkage.
