Check Spark Plug
Annually or every 100 hours of operation, remove the
spark plug, check condition, and reset the gap or
replace with new plug as necessary. The original plug
is an NGK BPR4ES. The Champion
NGK plug is RN14YC. The service replacement is
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 14.
4. Reinstall the spark plug into the cylinder head.

Battery Charging
Batteries produce explosive hydrogen gas while being
®
equivalent of that
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
