4. When servicing the foam element, check the
condition of the paper element. Clean it by gently
tapping it on a flat surface or replace it if needed.
5. Install the foam element, paper element, and air
cleaner cover.
Important: Do not operate the engine without
the air cleaner element because extreme engine
wear and damage will likely result.

2. Remove the oil filter (Figure 45). Apply a light coat
of clean oil to the new filter gasket.
3. Screw the filter on by hand until the gasket contacts
the filter adapter, then tighten 1/2 to 3/4 turn
further. Do not overtighten.
4. Add oil to the crankcase; refer to
Checking the Engine Oil (page 23).
5. Dispose of the used oil properly.

Replacing the Spark Plugs

Service Interval: Every 800 hours
The recommended air gap is 0.030 inch (0.76 mm)
The correct spark plug to use is a Champion RC 14YC.
Note: The spark plug usually lasts a long time; however,
the plug should be removed and checked whenever the
engine malfunctions.
1. Clean the area around the spark plugs so foreign
matter cannot fall into the cylinder when the spark
plug is removed.
2. Pull the spark plug wires off of the spark plugs and
remove the plugs from the cylinder head.
3. Check the condition of the side electrode, center
electrode, and center electrode insulator to ensure
that there is no damage.
Important: Replace a cracked, fouled, dirty, or
otherwise malfunctioning spark plug. Do not
sand blast, scrape, or clean electrodes by using a
wire brush because grit may eventually release
from the plug, fall into the cylinder, and damage
the engine.
4. Set the air gap between the center and side of the
electrodes at 0.030 inch (0.76 mm) (Figure 46).
5. Install the correctly gapped spark plug with gasket
seal, and tighten the plug to 200 in-lb (23 N-m). If a
torque wrench is not used, tighten the plug firmly.
