Check Spark Plugs
Every 200 hours of operation, remove the spark plugs,
check condition, and reset the gap or replace with new
plugs as necessary. The standard spark plug is a
®
Champion
RC12YC (Kohler Part No. 12 132 02-S). RFI
compliant engines use a Champion
Part No. 25 132 14-S) spark plug. A high-performance
spark plug, Champion
®
Series engines, Kohler Part No. 25 132 12-S) is also
available. Equivalent alternate brand plugs can also
be used.
1. Before removing the spark plug, clean the area
around the base of the plug to keep dirt and
debris out of the engine.
2. Remove the plug and check its condition. Replace
the plug if worn or reuse is questionable.
NOTE: Do not clean the spark plug in a machine
using abrasive grit. Some grit could
remain in the spark plug and enter the
engine causing extensive wear and
damage.
3. Check the gap using a wire feeler gauge. Adjust
the gap to 0.76 mm (0.030 in.) by carefully
bending the ground electrode. See Figure 16.
4. Reinstall the spark plug into the cylinder head.
Torque the spark plug to 24.4-29.8 N·m
(18-22 ft. lb.).

Battery Charging
WARNING: Explosive Gas!
Batteries produce explosive hydrogen gas while being charged.
To prevent a fire or explosion, charge batteries only in well
ventilated areas. Keep sparks, open flames, and other sources of
ignition away from the battery at all times. Keep batteries out of
the reach of children. Remove all jewelry when servicing
batteries.
Before disconnecting the negative (-) ground cable, make sure
all switches are OFF. If ON, a spark will occur at the ground
cable terminal which could cause an explosion if hydrogen gas
or gasoline vapors are present.
Fuel System
WARNING: Fuel System Under Pressure!
The EFI fuel system operates under high pressure, and the fuel
filter and fuel line used must be approved system components
only. Use of substitute parts can result in system failure,
gasoline leakage and possible explosion.
Fuel Filter
Carbureted Engines: Most engines are equipped with
an in-line fuel filter. Periodically inspect the filter and
replace with a genuine Kohler filter every 200
operating hours.
EFI Engines: A special, high volume, high pressure
filter with greater filtration capabilities and internal
surface area is used. See Figure 17.

Replacement is recommended every 1500 hours, or
more frequently under extremely dusty or dirty
conditions. When replacement is necessary, always
use genuine Kohler parts.
