4. Clean around the spark plugs to prevent dirt from

falling into the engine and potentially causing
damage.

5. Remove the spark plugs and the metal washers.

Checking the Spark Plugs

1. Look at the center of the spark plugs (Figure 30).

If you see light brown or gray on the insulator, the
engine is operating properly. A black coating on the
insulator usually means that the air cleaner is dirty.

2. If needed, clean the spark plug with a wire brush to

remove carbon deposits.

Important:

Always replace the spark plugs

when it has a black coating, worn electrodes,
an oily film, or cracks.

3. Check the gap between the center and side electrodes

(Figure 30). Bend the side electrode (Figure 30) if
the gap is not correct.

Installing the Spark Plugs

1. Install the spark plugs and the metal washer. Ensure

that the air gap is set correctly.

2. Tighten the spark plugs to 16 ft-lb (22 N•m).

3. Connect the wires to the spark plugs (Figure 30).

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.

Draining the Fuel Tank

1. Park the machine on a level surface, to assure fuel

tank drains completely. Then disengage the power
take off (PTO), set the parking brake, and turn the
ignition key to

off

. Remove the key.

2. Close the fuel shut-off valve at the fuel tank

(Figure 31).

3. Squeeze the ends of the hose clamp together

and slide it up the fuel line away from fuel filter
(Figure 31).

4. Pull the fuel line off the fuel filter (Figure 31). Open

the fuel shut-off valve and allow the gasoline to drain
into a gas can or drain pan.

Note:

Now is the best time to install a new fuel filter

because the fuel tank is empty. Refer to Replacing
the Fuel Filter.

5. Install the fuel line onto the fuel filter. Slide the hose

clamp close to the valve to secure the fuel line.
