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.
