wrench, remove
the spark plug.

3. Inspect the spark plug: If the electrode is

oily, clean it using a clean, dry rag. If the

electrode has deposits on it, polish it using

emery paper. If the white insulator is cracked or chipped, the spark plug needs to be replaced.

4.When installing a new spark plug, adjust the plug’s gap to the specification on the Specifications chart. Do not pry against the electrode, the spark plug can be damaged.

5.Install the new spark plug or the cleaned spark plug into the engine. Gasket-style: Finger-tighten until the gasket contacts the cylinder head, then about 1/2-2/3 turn more.

Non-gasket-style: Finger-tighten until the plug contacts the head, then about 1/16 turn more.

NOTICE: Tighten the spark plug properly. If loose, the spark plug will cause the engine to overheat. If overtightened, the threads in the engine block will be damaged.

Storage

Setup

When the equipment is to remain idle for longer than

20 days, prepare the engine for storage as follows:

1.CLEANING:

Wait for engine to cool, then clean engine with dry cloth. NOTICE: Do not clean using water. The water will gradually enter the engine and cause rust damage.

Apply a thin coat of rust preventive oil to all metal parts.

2.FUEL:

WARNING! To prevent serious injury from fire:

Drain the fuel tank in a well-ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before draining fuel.

Do not smoke.

a. Place a funnel leading to a proper gasoline container below the carburetor.

b.Remove the drain bolt from

the bottom of
the carburetor
bowl and allow	Cylinder
the fuel to drain.

If present on	Drain Plug
your model,

remove the small sediment cup next to the bowl and allow the fuel to drain from there as well.

c.Open the fuel valve. After all fuel has drained, reinstall the drain bolt and sediment cup (if equipped). Tighten securely.

3.Lubrication:

a.Change engine oil.

b.Clean out area around spark plug.

Remove spark plug and pour one tablespoon of engine oil into cylinder through spark plug hole.

c.Replace spark plug, but leave spark plug cap disconnected.

d.Pull Starter Handle to distribute oil in cylinder. Stop after one or two revolutions when you feel the piston start the compression stroke (when you start to feel resistance).

4.Battery:

Disconnect battery cables (if equipped). Recharge batteries monthly while in storage.

5.STORAGE AREA:

Cover and store in a dry, level, well-ventilated area out of reach of children. Storage area should also be away from ignition sources, such as water heaters, clothes dryers, and furnaces.

6.After Storage:

Before starting the engine after storage, keep in mind that untreated gasoline will deteriorate quickly. Drain the fuel tank and change to fresh fuel if untreated gasoline has been sitting for

amonth, if treated gasoline has been sitting beyond the fuel stabilizer’s recommended time period, or if the engine does not start.
