F.

Alternator (Optional)

For alternator related electrical problems such as:

• Inoperative Starter

• Discharged Battery 

• Fuse Replacement

• Alternator Maintenance/Repairs

See your equipment manufacturer’s instructions and an 
Authorized TecumsehPower Servicing Dealer.

G. Carburetor

If you think your carburetor needs adjusting, see your 
nearest Authorized TecumsehPower Servicing Dealer. 
Engine performance should not be affected at altitudes up 
to 7,000 feet (2,134 meters). For operation at higher 
elevations, contact an Authorized TecumsehPower 
Servicing Dealer.

H. Engine Speed

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.

Running the engine faster than the speed set at the factory 
can be dangerous and will 

VOID THE ENGINE WARRANTY.

I.

Adjustments

DO NOT make any engine adjustments. Factory settings 
are satisfactory for most conditions. If adjustments are 
needed, contact your Authorized TecumsehPower 
Servicing Dealer.

VIII. Transporting Your Engine

NEVER transport this engine inside 
another vehicle or in any enclosed 

space if there is any gasoline in the tank. Fuel vapor or 
spilled fuel may ignite leading to serious injury or death.

If there is fuel in the fuel tank, close the fuel shut-off valve, 
if equipped, and transport the engine upright in an open 
vehicle, such as an open trailer or open bed of a pickup 
truck.

If you do not have an open vehicle and have to transport 
the engine upright in a closed vehicle, follow these steps 
for emptying the fuel tank before transporting:

1.

Empty fuel tank by using a commercially available 
suction device designed for use with gasoline. 

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

siphon fuel by mouth.

2.

Drain fuel into an approved red GASOLINE container, 
being careful to avoid spilling.

3.

Run the engine until remaining fuel is consumed.

NEVER leave the engine unattended 
when it is running and NEVER run 

engine in enclosed areas to avoid death or serious injury.
