bent or damaged.

cleaner base. Make sure it is secured and not bent

Ignition System

This engine is equipped with a dependable electronic

magneto ignition system. Other than periodically

checking/replacing the spark plug, 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 plug, see your

Kohler Engine Service Center for trouble analysis.

Check Spark Plug

Yearly or every 100 hours of operation, remove the

spark plug, check condition, and reset the gap or

replace with a new plug as necessary. The original

spark plug is a Champion

equivalent is a Kohler Part No. 12 132 02-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 21.
