Installing the Foam and Paper Elements
Important To prevent engine damage, always operate
the engine with the complete foam and paper air cleaner
assembly installed.
1. Carefully slide the foam element onto the paper air
cleaner element (Fig. 22).
2. Slide the air cleaner assembly onto the long rod. Screw
the rubber nut finger-tight against the air cleaner
(Fig. 23).
Note: Make sure that the rubber seal is flat against the air
cleaner base.

Servicing the Spark Plug

Install a new spark plug after every 100 operating hours.
Check the spark plug after every 25 operating 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 and a
gapping tool/feeler gauge to check and adjust the air gap.
Type: Champion RJ-19LM (or equivalent)
Air Gap: 0.030 in. (0.762 mm)
Removing the Spark Plug
1. Disengage the PTO, shift into neutral, set the parking
brake, stop the engine, and remove the ignition key.
2. Open the hood.
3. Pull the wire off of the spark plug (Fig. 26). Clean
around the spark plug to prevent dirt from falling into
the engine and potentially causing damage.
4. Remove the spark plug and metal washer.

Checking the Spark Plug
1. Look at the center of the spark plug (Fig. 27). 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. Always replace
the spark plug when it has a black coating, worn electrodes,
an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 27). Bend the side electrode (Fig. 27) if the gap is
not correct.
