HOT AIR TUBE REMOVAL/INSTALLATION

(applicable types)
Normally use the engine with the hot air tube installed, or it
•
can cause icing.
When the ambient temperature is high (86°F/30°C or above),
•
be sure to remove the hot air tube in the following procedure
before operating the engine.
Operating the engine with the hot air tube installed can cause
overheat of the engine.
• Release the hot air tube from the tube clip and disconnect it
from the hot air duct before removing the top cover for
maintenance, etc. After installing the top cover, be sure to
reinstall the hot air tube securely in the original position.
1. Remove the air cleaner cover (see page 5).
2. See Figure 15, page A-4.
Release the hot air tube [1] from the clip [2] at the engine
cover and pull the hot air tube out of the hot air duct [3] on
the engine cover.
3. See Figure 16, page A-4.
Remove the hot air joint [1] from the air cleaner case.

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.
Adding a Gasoline Stabilizer to Extend Fuel Storage Life
When adding a gasoline stabilizer, fill the fuel tank with fresh
gasoline. If only partially filled, air in the tank will promote fuel
deterioration during storage. If you keep a container of gasoline
for refueling, be sure that it contains only fresh gasoline.
1. Add gasoline stabilizer following the manufacturer's
instructions.
2. After adding a gasoline stabilizer, run the engine outdoors
for 10 minutes to be sure that treated gasoline has replaced
the untreated gasoline in the carburetor.
3. Stop the engine.
