3. Slide the foam element off of the paper
cartridge and clean it as follows:
A. Wash the foam element in a solution of
liquid soap and warm water, squeezing it
to remove dirt, but do not twist because
it may tear.
B. Rinse the element thoroughly in clear water.
C. Dry the element by wrapping it in a clean
rag, squeezing the rag and element.
Important: Do not oil either element.
4. Clean the paper element by tapping it on a
hard surface to knock the dirt out of it.
Important: Do not wash the paper
element, or clean it with solvent such as
kerosene. Do not use pressurized air to
clean it. Cleaning it with any of these
methods could damage the element.
5. Install the foam element over the paper
element.
6. Install the elements into the air cleaner.
7. Install the air cleaner cover, securing it with
the knob.

otherwise extreme engine wear and
damage will result.

Servicing the Spark Plug

Check the spark plug after every 100 operating
hours or yearly whichever comes first. Ensure 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. Install a new spark
plug if necessary.
Type: Champion RCJ-8 or equivalent.
Air Gap: 0.030 inch (0.76 mm)
Removing the Spark Plug

2. Pull the wire off of the spark plug (Figure 29).

3. Clean the area around the spark plug.
4. Remove the plug from the cylinder head.
Checking the Spark Plug
1. Look at the center of the spark plug (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 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.
