SPARK PLUG

Recommended Spark Plug:
The recommended spark plug has the correct heat range for normal
engine operating temperatures.
Incorrect spark plugs can cause engine damage.
If the engine has been running, let it cool before servicing the spark
plugs.
For good performance, the spark plugs must be properly gapped and
free of deposits.
1. Disconnect the spark plug caps, and remove any dirt from around the
spark plug area.
2. Remove the spark plugs with a 5/8-inch spark plug wrench.

3. Inspect the spark plugs. Replace
them if damaged, badly fouled, if
the sealing washer is in poor
condition, or if the electrode is
worn.
4. Measure the spark plug electrode
gaps with a wire-type feeler
gauge. Correct the gap, if
necessary, by carefully bending
the side electrode.
The gap should be:
0.7–0.8 mm
(0.028–0.031 in)
5. Install the spark plugs carefully, by
hand, to avoid cross-threading.
6. After the spark plug is seated, tighten with a 5/8-inch spark plug
wrench to compress the sealing washer.
When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
When reinstalling the original spark plug, tighten 1/8–1/4 turn after
the spark plug seats to compress the washer.

A loose spark plug can overheat and damage the engine. Overtightening
the spark plug can damage the threads in the cylinder head.
7. Attach the spark plug caps to the spark plugs.

HELPFUL TIPS & SUGGESTIONS

STORING YOUR ENGINE

Storage Preparation
Proper storage preparation is essential for keeping your engine trouble-
free and looking good. The following steps will help to keep rust and
corrosion from impairing your engine's function and appearance, and
will make the engine easier to start when you use it again.
Cleaning
If the engine has been running, allow it to cool for at least half an hour
before cleaning. Clean all exterior surfaces, touch up any damaged paint,
and coat other areas that may rust with a light film of oil.
Using a garden hose or pressure washing equipment can force water into the
air cleaner or muffler opening. Water in the air cleaner will soak the air filter,
and water that passes through the air filter or muffler can enter the cylinder,
causing damage.
Fuel
Depending on the region where you operate your equipment, fuel
formulations may deteriorate and oxidize rapidly. Fuel deterioration and
oxidation can occur in as little as 30 days and may cause damage to the
carburetor and/or fuel system. Please check with your servicing dealer for
local storage recommendations.
Gasoline will oxidize and deteriorate in storage. Deteriorated gasoline
will cause hard starting, and it leaves gum deposits that clog the fuel
system. If the gasoline in your engine deteriorates during storage, you
may need to have the carburetor and other fuel system components
serviced or replaced.
The length of time that gasoline can be left in your fuel tank and
carburetor without causing functional problems will vary with such
factors as gasoline blend, your storage temperatures, and whether the
fuel tank is partially or completely filled. The air in a partially filled fuel
tank promotes fuel deterioration. Very warm storage temperatures
accelerate fuel deterioration. Fuel deterioration problems may occur
within a few months, or even less if the gasoline was not fresh when you
filled the fuel tank.
Fuel system damage or engine performance problems resulting from
neglected storage preparation are not covered under the Distributor's
Limited Warranty.
You can extend fuel storage life by adding a gasoline stabilizer that is
formulated for that purpose, or you can avoid fuel deterioration
problems by draining the fuel tank and carburetor.
