Prepping your Tecumseh Engine Powered Device for Storage

Gasoline can become stale in less than 30 days and form deposits that can hamper proper fuel flow and impede proper tecumseh engine operation. To prevent deposits from forming, all gasoline has to be removed from the fuel tank and the carburetor on the tecumseh engine.
 

CAUTION: Only drain the fuel into an approved container outdoors away from any combustion source. Make sure the engine has had enough time to cool down.

Remove the Gas:

1. Remove all gasoline from the fuel tank by running the engine until the engine stops. You can also drain 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. On engines with carburetor bowl drain, press upwards on it to drain the fuel out of the carburetor. The drain will be located on the bottom of the carburetor bowl.

3.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.

4. If Gasoline with Ethanol 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 will 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.

Oil Cylinder Bore:

1. Disconnect the spark plug wire and ground the wire to the engine. Remove the spark plug and put 1/2 ounce (14 ml) of clean engine oil into the spark plug hole.

2. Cover the spark plug hole with a shop towel.

3. Crank the engine over slowly several times. CAUTION: AVOID SPRAY FROM SPARK PLUG HOLE WHEN SLOWLY CRANKING ENGINE OVER.
 
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, cylinder head, cylinder cooling fins, carburetor, governor levers and linkage.

An Alternative to Draining the Fuel
 

CAUTION: Do not use fuel additive that has a methanol blend. This cause damage to your gaskets and seals if stored along time. Use an additive that has isopropyl instead.

An acceptable alternative to removing all gasoline is adding a fuel stabilizer 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.
 
CAUTION: Never Store an engine, with fuel, indoors in a poorly ventilated area with an ignition source nearby, be it a pilot light, spark, or an open flame.
