D. Cleaning/Replacing Air Filters
Your engine has an air cleaner which helps prevent
premature engine wear and failure. NEVER run engine
without complete air cleaner installed on engine. The filters
in the air cleaner periodically need to be cleaned or
replaced.
NOTE
Contact your Authorized Tecumseh Servicing Dealer for a
Tecumseh Air Cleaner.

F. Carburetor
If you think your carburetor needs adjusting, see the
nearest Authorized Tecumseh 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 Tecumseh Servicing Dealer.
G. 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.
H. Adjustments
Do not make any engine adjustments. Factory settings are
satisfactory for most conditions. If adjustments are needed,
contact your Authorized Tecumseh Servicing Dealer.
