TecumsehPower Company is no longer owned by Tecumseh Products Company nor is it associated or affiliated in any
way with Tecumseh Products Company .
Read equipment manufacturer’s manual and this
material thoroughly before using this engine. Failure to
do so can result in serious injury or death. Consult your
local Authorized TecumsehPower Servicing Dealer, call
1-800-558-5402, or go to www.TecumsehPower.com for
additional information.
A. Avoid Carbon Monoxide Poisoning
All engine exhaust contains
carbon monoxide, a deadly
gas. Breathing carbon
monoxide can cause
headaches, dizziness,
drowsiness, nausea, confusion
and eventually death.
Carbon monoxide is a colorless, odorless, tasteless gas
which may be present even if you DO NOT see or smell
any engine exhaust. Deadly levels of carbon monoxide can
collect rapidly and you can quickly be overcome and
unable to save yourself. Also, deadly levels of carbon
monoxide can linger for hours or days in enclosed or
poorly-ventilated areas. If you experience any symptoms of
carbon monoxide poisoning, leave the area immediately,
get fresh air, and SEEK MEDICAL TREATMENT.
To prevent serious injury or death from carbon monoxide:
• NEVER run engine indoors. Even if you try to
ventilate engine exhaust with fans or open windows
and doors, carbon monoxide can rapidly reach
dangerous levels.
• NEVER run engine in poorly-ventilated or partially
enclosed areas such as barns, garages,
basements, carports, under dwellings, or in pits.
• NEVER run engine outdoors where engine exhaust
can be drawn into a building through openings such
as windows and doors.
B. Avoid Gasoline Fires
Gasoline (fuel) vapors are highly flammable
and can explode. Fuel vapors can spread
and be ignited by a spark or flame many feet
away from engine. To prevent injury or death
from fuel fires, follow these instructions:
• 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.
• NEVER remove fuel fill cap or add fuel when engine
is running.
• NEVER start or operate the engine with the fuel fill
cap removed.
• Allow engine to cool before refueling.
• NEVER fill fuel tank indoors. Fill fuel tank outdoors
in a well-ventilated area.
• DO NOT smoke while refueling tank.
• Use only an approved red GASOLINE container
to store and dispense fuel. TecumsehPower
Company recommends purchasing gasoline in
containers with a capacity of 2.5 gallons or less.
Small containers are easier to handle and help
eliminate spillage during refueling.
• DO NOT pour fuel from engine or siphon fuel by
mouth. T o empty the fuel t ank, see "I. Draining Fuel"
instructions on page 14.
C. Adult Supervision of Operation, Refueling
and Maintenance
The manufacturer of the equipment may provide
information about who is allowed to use this engine (see
equipment manufacturer’s manual). NOT everyone who is
allowed to use this engine is capable of safely and
responsibly operating, maintaining and/or fueling it.
TecumsehPower Company recommends the following:
• An adult should fuel this engine. NEVER allow
children to refuel this engine. See "C. Filling Fuel
Tank" instructions on page 5.
• An adult should perform maintenance on this
engine. See "VII. Maintenance" instructions on
page 10. Only allow children to perform maintenance if an adult has determined they are
experienced and capable of such operation.
• An adult should start the engine. See "G. Avoid
Accidental Starts" instructions on page 2. Only
allow children to start the engine if an adult has
determined they are experienced and capable of
such operation.
• To avoid unsupervised operation of the engine,
especially by children, NEVER leave it unattended
when it is running. Remove ignition key, if equipped.
D. Stay Away from Rotating Parts
NEVER operate the engine with an unguarded engine shaft
or flywheel. See Figures 1 and 2 on page 2.
The equipment manufacturer may
attach a sprocket and chain or pulley
and belt to the engine shaft. If these
parts are NOT properly guarded, or if
you are NOT sure whether they are
properly guarded, DO NOT use your
engine; contact the equipment
manufacturer. Hands, feet, hair,
jewelry, clothing, etc.,can become
entangled in rotating parts, leading to
serious injury or death. To avoid
serious injury or death, be sure the
flywheel guard is in place. See Figures
1 and 2 on page 2.
181-1032-14Page 1
E.DO NOT Modify Engine
S
T
O
P
To avoid serious injury or death, DO NOT modify en gine in
any way. Tampering with the governor setting can lead to a
runaway engine and cause it to operate at unsafe speeds.
NEVER tamper with factory setting of engine governor.
!
WARNING
Use of this engine on fun-carts, go-kar ts, o r mini-bikes
can result in serious injury or death. TecumsehPower
Company manufactures the Power Sport line of engines
for use in such applications. Consult your local Authorized
TecumsehPower Servicing Dealer, call 1-800-558-5402,
or visit www.TecumsehPower .com for additional information.
F.Avoid Burns and Fire from Hot Surfaces
The muffler and other engine parts become
extremely hot during operation and remain
hot after the engine has stopped.
Figure 1. DO NOT use Without Engine Shaft Guard
1
• To avoid severe burns on contact,
STAY AWAY from hot areas of
engine. DO NOT operate the engine
without the muffler guard in place,
if equipped.
• To reduce the risk of fire keep all materials that can
burn, including grass and leaves, away from muffler
and rest of engine. DO NOT operate, idle or park
engine powered equipment in long dry grass or
other dry ground cover.
G.Avoid Accidental Starts
To prevent accidental starting when working on equipment
always:
• Carefully disconnect spark plug wire and keep it
away from spark plug. See Figures 3 and 4.
• Keep the disconnected spark plug wire
securely away from metal par ts where arcing
could occur.
• Carefully attach the spark plug wire to the
grounding post, if provided.
• Disconnect battery at negative terminal first, if
engine is equipped with a DC electric starter.
• Turn all engine switches to “OFF” position.

A. Oil
To operate engine you need to use a clean, high quality,
detergent oil. For recommended engine oil, see Table 1 on
page 3. In addition, you need to be sure the oil sump
contains the correct amount of oil to operate properly.
NOTES
The oil sump capacity is 21 ounces or 1-1/4 U.S. Pints
(.62 liters).
Be sure original container is marked A.P.I. Service “SL/SJ”.
Using multigrade oil above 32°F (0°C) will increase oil
consumption. SAE 10W40 is NOT recommended.
Special-formulated oils are available at your Authorized
TecumsehPower Servicing Dealer.
B. Fuel
Use unleaded regular, unleaded premium or reformulated
automotive fuel only. You may use gasoline containing the
components identified in Table 2.
• DO NOT use leaded fuel.

over from last season or stored for long periods.
• NEVER mix oil with fuel.
• DO NOT use fuel containing Methanol
(Wood Alcohol).
CAUTION
TecumsehPower engines. Alternative fuels with high
alcohol content can cause hard starting, poor engine
performance, and may cause internal engine damage.
Damage and/or performance problems that occur fro m use
of fuels other than those listed in the Operator’s Manuals will
not be considered warranty.
The use of alternative fuels such as E85
or E20 are NOT recommended for use in
• Check oil level before each use and every 5
operating hours when engine is warm. Check oil
level more frequently during engine break-in.
• Keep oil level between “FULL” and “ADD” marks on
dipstick. See Figure 7.
• Insure oil fill cap/plug is tightened securely.
