Seasonal Storage

If engine is to be unused for more than a month, prepare
engine as indicated below:

Fuel System

Fuel stored in the tank will gradually deteriorate, leaving
gum deposits which will clog the carburetor or fuel
system. To avoid these problems, treat the fuel system
in one of the two following methods:

Method 1

Tecumseh recommends using UL
line stabilizer as an acceptable method of minimizing
formation of fuel gum deposits during storage; This prod-
uct is available from your Authorized Tecumseh Servic-
ing Dealer.
1. Add fuel preservative/stabilizer according to
manufacturers instructions.
2. Run engine at least 10 minutes after adding
stabilizer to allow it to reach carburetors.
NOTES
Always follow mix ratio found on stabilizer container.
Failure to do so may result in equipment damage.
DO NOT drain stabilizer from carburetor. Doing so may
result in gum deposits and/or corrosion and cause
equipment malfunction.
Instead of using a fuel preservative/stabilizer, you can
empty the fuel tank as follows:

Method 2

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. Drain remaining fuel from carburetor by pressing up
on bowl drain if present.

Oil

Change oil if not changed within the last 3 months. See
"Checking and Changing Oil" instructions under "Mainte-
nance and Adjustments".

Lubricating Cylinder Bore

When lubricating cylinder bore,
WARNING
fuel may spray from the spark
plug hole. To prevent serious injury from fuel
fires, follow these instructions:
1. Disconnect spark plug wire and keep it away from
spark plug by attaching it securely to grounding
post.
2. Remove spark plug.
3. Squirt 1oz. (30ml) of clean engine oil into spark
plug hole.
4. Cover spark plug hole with rag to prevent fuel from
spraying from spark plug hole when starter rope is
pulled.
5. Grasp starter cord handle and pull out slowly using
a full arm stroke. Repeat once. (This will distribute
oil throughout the cylinder to prevent corrosion
during storage.)
6. Install spark plug.
Connect spark plug wire before attempting to start en-
gine once engine is out of storage.
