Engine Identification Numbers
When ordering parts, or in any communication involving
an engine, always give the
Model, Specification, and
Serial Numbers
of the engine.
The engine identification numbers appear on a decal
affixed to the engine shrouding. Include letter suffixes, if
there are any.
Record your engine identification numbers on the
identification label below (Figure 4) for future reference.
Fuel Recommendations
WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can
explode if ignited. Store gasoline only in approved
containers, in well ventilated, unoccupied buildings,
away from sparks or flames. Do not fill the fuel tank
while the engine is hot or running, since spilled fuel
could ignite if it comes in contact with hot parts or
sparks from ignition. Do not start the engine near spilled
fuel. Never use gasoline as a cleaning agent.
General Recommendations
Purchase gasoline in small quantities and store in
clean, approved containers. A container with a capacity
of 2 gallons or less with a pouring spout is
recommended. Such a container is easier to handle
and helps eliminate spillage during refueling.
Do not use gasoline left over from the previous season,
to minimize gum deposits in your fuel system and to
insure easy starting.
Do not add oil to the gasoline.
Do not overfill the fuel tank. Leave room for the fuel to
expand.
Fuel Type
For best results use only clean, fresh,
unleaded
gasoline with a pump sticker octane rating of 87 or
higher. In countries using the Research method, it
should be 90 octane minimum.
Unleaded gasoline is recommended as it leaves less
combustion chamber deposits. Leaded gasoline may be
used in areas where unleaded is not available and
exhaust emissions are not regulated. Be aware
however, that the cylinder head will require more
frequent service.
Gasoline/Alcohol blends
Gasohol (up to 10% ethyl alcohol, 90% unleaded
gasoline by volume) is approved as a fuel for Kohler
engines. Other gasoline/alcohol blends are not
approved.
Gasoline/Ether blends
Methyl Tertiary Butyl Ether (MTBE) and unleaded
gasoline blends (up to a maximum of 15% MTBE by
volume) are approved as a fuel for Kohler engines.
Other gasoline/ether blends are not approved.

The Emission Compliance Period referred to on the
Emission Control or Air Index label indicates the
number of operating hours for which the engine has
been shown to meet CARB emission requirements. The
following table provides the Engine Compliance Period
(in hours) associated with the category descriptor found
on the certification label.
