3.4 Fuel System
3.4.1 Fuel Specifications
Use a clean, good quality unleaded fuel with an octane
number of 87. Use fresh gasoline to ensure it is blended
for the season and to reduce the possibility of the
formation of gum deposits that could clog the fuel
system. Do not use gasoline left over from the previous
season.
Kohler Co. recommends unleaded fuel because it
leaves fewer combustion chamber deposits. Never mix
oil with fuel.
Note: Consult the engine owner’s manual for
oxygenated fuel recommendations.
3.4.2 Carburetor/Choke Lubrication
At the interval specified in the service schedule,
lubricate the carburetor and choke linkage using a light
oil. See Section 1, Service Views for the carburetor and
choke linkage locations.
3.4.3 Carburetor Adjustment
The carburetor is factory-set. No adjustments are
possible.
