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.

Removing the Spark Plug(s)
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to off.
Remove the key.
2. Pull the wire(s) off the spark plug(s) (Figure 40).
Now clean around the spark plug(s) to prevent

Checking the Spark Plug
1. Look at the center of the spark plug(s)
(Figure 41). 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.
Important:
Never clean the spark
plug(s). Always replace the spark plug(s)
when it has: a black coating, worn
electrodes, an oily film, or cracks.

if the gap is not correct.
Installing the Spark Plug(s)
1. Install the spark plug(s) and metal washer.
Make sure the air gap is set correctly.
2. Tighten the spark plug(s) to 30 ft-lb (41 N·m).

Fuel System
Maintenance
Servicing the Fuel Tank
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and
others and can damage property.
• Drain gasoline from the fuel tank when
the engine is cold. Do this outdoors in
an open area. Wipe up any gasoline that
spills.
• Never smoke when draining gasoline,
and stay away from an open flame or
where a spark may ignite the gasoline
fumes.
