EFI Engines: A special, high volume, high pressure

filter with greater filtration capabilities and internal

surface area is used. See Figure 24.

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

Carbureted Engines: 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 10-S.
