E. Do Not Modify Engine

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

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, 

NEVER operate the engine without 
the muffler guard in place, and avoid 
hot areas of the engine. 

• 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 
the engine application in long dry grass or other dry 
ground cover.

G. Avoid Accidental Starts

To prevent accidental starting when working on equipment 
always:

• Disconnect spark plug wire and keep it away from 

spark plug. See Figure 2.

• Keep the disconnected spark plug wire 

securely away from metal parts where arcing 
could occur. 

• Attach the spark plug wire to the grounding 

post if provided. See Figure 3.

• Disconnect battery at negative terminal first, if 

engine is equipped with an electric starter.

• Turn off all engine switches.
• Remove ignition key if provided.

H. Use Hearing Protection

Engine noise may cause hearing damage. Always wear 
hearing protection when operating an engine.

Use of this engine on fun-carts, go-karts, or mini-bikes 
can result in serious injury or death. Tecumseh 
manufactures the Power Sport line of engines for use in 
such applications. Consult your local Authorized 
Tecumseh Servicing Dealer, call 1-800-558-5402, or go
