To avoid serious injury or death, DO NOT modify engine 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-karts, or 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.
•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. TecumsehPower Company offers a muffler guard for all 4-Cycle Snow King Engines. Consult your local Authorized TecumsehPower Servicing Dealer or call 1-800-558-5402 for additional information. See Figure 2.
•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.
OH318SA/OH358SA OH195SA/OH195SP
LH195SA/LH195SP LH318SA/LH358SA
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 parts 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.
•Remove ignition key, if provided.
H.Use Hearing Protection
Engine noise may cause hearing damage. Always wear hearing protection when operating an engine.

A. Oil
To operate your engine you need to use a clean, high quality, detergent oil. For recommended engine oil, see Table 1. In addition, you need to be sure the oil sump contains the correct amount of oil to operate properly. For recommended oil sump capacity, see Table 2.
NOTES
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.

Use unleaded regular, unleaded premium or reformulated automotive fuel only. You may use gasoline containing the components identified in Table 3.
•DO NOT use leaded fuel.
•Fuel must be fresh and clean. NEVER use fuel left over from last season or stored for long periods.
•NEVER mix oil with fuel.
•DO NOT use fuel containing Methanol (Wood Alcohol).
The use of alternative fuels such as E85 CAUTION or E20 are NOT recommended for use in
TecumsehPower engines. Alternative fuels with high alcohol content can cause hard starting, poor engine performance, and may cause internal engine damage.
NOTE
Damage and/or performance problems that occur from use of fuels other than those listed in the Operator’s Manuals will not be considered warranty.
To avoid engine damage, it is important to:
•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 oil fill cap/dipstick or to point of overflow on engines with an oil fill cap/plug. See Figure 7.
•Be sure oil fill cap/dipstick or oil fill cap/plug is tightened securely.
NOTES
DO NOT overfill oil filler. Doing so may result in oil carryover to the equipment and cause malfunction or damage.
DO NOT allow oil level to fall below the “ADD” mark on oil fill cap/dipstick. Doing so may result in equipment malfunction or damage.
Contact your Authorized TecumsehPower Servicing Dealer for TecumsehPower Oil.
Some engines are equipped with an oil fill cap/dipstick or oil fill cap/plug (see equipment manufacturer’s instructions). To change the oil on your engine, see "B. Changing Oil" instructions on page 17.

engine. 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:
2.Be sure engine is outdoors and in a well-ventilated area.
NOTE
For recommended fuel, see Table 3 and "III. Oil and Fuel Specifications" instructions on page 4. Afterward, continue reading instructions below.
5.Replace fuel fill cap securely and wipe up spilled fuel before starting engine. If fuel is spilled DO NOT start engine. Move machine away from area of spillage.
Avoid creating any source of ignition until fuel vapors are gone.
NOTE
Replace a damaged or missing fuel fill cap only with a genuine TecumsehPower replacement Fuel Fill Cap. Failure to do so may VOID YOUR WARRANTY.
See Figure 15.
F.Electrical Power
NOTES
When connecting power cord, always connect power cord to switch box on engine first; then into outlet. See Figure 17.
For European 220V AC applications use an appropriate grounded extension lead available locally.
Determine what type of power source outlet you will be connecting the power cord to, before you start your engine. See "A. Engines with Electric Starters" instructions on page 10.
