IX. Storing Your Engine

A. Short-Term/Seasonal Storage

I. Clean Engine

Before servicing the engine remove the air cleaner cover 
and/or blower housing. Discard grass clippings, dirt and 
debris from the following areas: 

• Cooling Fins

• Air Intake Screen 

• Levers 

• Linkage 

• Guards

• Carburetor

• Head

Removing debris will insure adequate cooling, correct 
engine speed and reduce the risk of fire.

II. Fuel Storage

NEVER store engine with fuel in fuel 
tank inside a building with potential 

sources of ignition such as hot water and space heaters, 
clothes dryers, electric motors, etc. Failure to do so may 
result in an explosion and result in death or serious injury.

 NOTES

If engine fuel stored in the gas tank and/or an approved gas 
container is to be unused without gasoline stabilizer for 
more than 15-30 days, prepare it for short-term/seasonal 
storage. See "IV. Fuel Treatment" instructions.

If engine fuel is to be stored for more than one season, 
without gasoline stabilizer, it will gradually deteriorate. Also, 
if it is stored in the engine’s gas tank without gasoline 
stabilizer it is likely that your carburetor will have gum 
deposits, a clogged fuel system and will void your warranty. 
Prepare the fuel for extended storage. See "B. Extended 
Storage" instructions. Afterward, continue reading 
instructions below.

If you operate the engine during all 4 seasons, it is NOT 
necessary to lubricate the cylinder bore. 

III. Fuel System

To avoid stale gas and carburetor problems, treat the fuel 
system in the following method below: 

 NOTES

Tecumseh recommends using 

ULTRA-FRESH™

 or Fuel 

Saver Plus Gasoline Stabilizer plus Fuel System Cleaner as 
an acceptable method of minimizing formation of fuel gum 
deposits during storage. This product is available from your 
Authorized Tecumseh Servicing Dealer.

Always follow mix ratio found on stabilizer container. Failure 
to do so may result in equipment damage.

It is NOT necessary to drain stabilized gas from carburetor. 

IV. Fuel Treatment

1. Add fuel stabilizer according to manufacturer’s 

instructions.

2. Run engine at least 10 minutes after adding stabilizer 

to allow it to reach carburetor.

NEVER store the engine with fuel in 
the fuel tank inside a building with 

potential sources of ignition such as hot water and space 
heaters, clothes dryers, electric motors, etc.

 NOTE

Instead of using a fuel preservative/stabilizer, you can 
empty the fuel tank as described under "I. Draining Fuel" 
instructions. See "B. Extended Storage" instructions.

B. Extended Storage

I. Draining Fuel

 NOTES

Clean debris from engine before draining fuel from 
carburetor. See "I. Clean Engine" instructions. Afterward, 
continue reading instructions below.

If you have prepared your fuel for short-term storage it is 
NOT necessary to drain fuel that contains stabilizer from 
your carburetor. See "A. Short-Term/Seasonal Storage" 
instructions.

To avoid severe injury or death, 
DO NOT pour fuel from engine or 

siphon fuel by mouth.
1. To prevent serious injury from fuel fires, empty fuel tank 

by running engine until it stops from lack of fuel. DO 
NOT attempt to pour fuel from engine.

2. Run the engine while waiting until the remaining fuel is 

consumed. 

NEVER leave the engine 
unattended when it is running and 

NEVER run engine in enclosed areas.
3. Begin servicing the cylinder bore. See "II. Oil Cylinder 

Bore" instructions on page 22.
