Ignition System
This engine is equipped with an electronic CD ignition
system. Other than periodically checking/replacing the
spark plugs, no maintenance or adjustments are
necessary or possible with this system.
In the event starting problems should occur which are
not corrected by replacing the spark plugs, see your
Kohler Engine Service Dealer for trouble analysis.
Check Spark Plugs
Annually or every 200 hours of operation (whichever
comes first), remove the spark plugs, check condition,
and reset the gap or replace with new plugs as
necessary. Every 500 hours of operation replace the
spark plugs. The standard spark plug is a Champion
®
RC14YC (Kohler Part No. 66 132 01-S). 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 23.
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.
NOTE: Do not apply 12 volt DC to kill terminal of
ignition module.
Fuel Filter
Most engines are equipped with an in-line fuel filter.
Periodically inspect the filter and replace every 200
operating hours. Use a genuine Kohler filter, Part No.
24 050 02-S.
