Servicing the Spark Plug

Service Interval: Every 200 hours
Make sure that the air gap between the center and
side electrodes is correct before installing the spark
plug.
Use a spark plug wrench for removing and installing
the spark plug(s) and a gapping tool/feeler gauge to
check and adjust the air gap. Install a new spark
plug(s) if necessary.
Type for all Engines: Kohler 25 132 14-c, Champion
XC12YC, or equivalent
Air Gap: 0.75 mm (0.03 inch)
Removing the Spark Plug
1. Park the machine on a level surface, disengage
the PTO, and engage the parking brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Remove the spark plug as shown in
Figure 43
Checking the Spark Plug
Important:
Always replace the spark plug(s) when it has a
black coating, worn electrodes, an oily film, or
cracks.
If you see light brown or gray on the insulator, the
engine is operating properly. A black coating on the
insulator usually means the air cleaner is dirty.
Set the gap to 0.75 mm (0.03 inch).
