7. Fill the fuel tank with the proper fuel/oil mix.
8. Start the engine and allow it run 3 - 5 minutes to reach operating temperature. Adjust the carburetor if necessary
(see Chapter 3 under "Service" for the final idle mixture adjustment procedure) and set the engine R.P.M.(s)
according to the specification number found on microfiche card # 30 or computer parts look up system.
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 unstable 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 adding a fuel stabilizer to the gasoline such as Tecumseh part number
730245. A fuel stabilizer is added to the fuel tank or storage container. Always follow the mix ratio and mixing procedure
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
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. Be careful not to damage the fuel line or the carburetor fitting.
CAUTION: DRAIN THE FUEL INTO AN APPROVED CONTAINER OUTDOORS, AND AWAY FROM ANY
OPEN FLAME OR COMBUSTIVE SOURCE. BE SURE THE ENGINE IS COOL.
2. If "Gasohol" has been used, complete the above procedure and then put 2 ounces (60 ml) of the recommended
fuel / oil mixture using regular unleaded gasoline into the fuel tank. Run the engine until it stops due to a lack of
fuel. If "Gasohol" is allowed to remain in the fuel system during storage, the alcohol content may cause gaskets
and seals to deteriorate.
Oil Cylinder Bore
1. Remove the spark plug wire from the spark plug. Pull the starter handle slowly until resistance is felt due to
compression pressure, then stop. Slowly release starter tension to prevent the engine from reversing due to
compression pressure.
2. Remove the spark plug, squirt 1/2 ounce (15 ml.) of clean 2-cycle engine oil into the spark plug hole.
3. Cover the spark plug hole with a shop towel and crank the engine over, slowly, several times.
4. Replace the spark plug and tighten (see step # 5 under Tune-Up Procedure for proper spark plug torque). Pull
the starter handle as performed in step # 1. The piston position blocks the cylinder ports, preventing atmospheric
air from entering and oil from leaving the cylinder bore during storage.
5. Replace the spark plug wire on the spark plug.
