3. Compressed Air Method
A. Blow compressed air from the inside to the outside
of a dry filter element. Do not exceed 100 psi
(689 kPa) to prevent damage to the element.
B. Keep the air hose nozzle at least 2 in. (5 cm) from
the filter and move the nozzle up and down while
rotating the filter element. Inspect the filter for holes
and tears by looking through the filter toward a
bright light.
4. Inspect the new filter for shipping damage. Check the
sealing end of the filter. Do not install a damaged filter.
5. Insert the new filter properly into the air cleaner body.
Make sure that the filter is sealed properly by applying
pressure to the outer rim of the filter when installing it.
Do not press on the flexible center of the filter.
6. Install the cover and secure the latches. Make sure that
the cover is positioned with the TOP side up.
Adjusting the Throttle Control
Proper throttle operation is dependent upon proper
adjustment of the throttle control. Before adjusting the
carburetor, ensure that the throttle control is operating
properly.
1. Pivot the seat upward and remove the engine shield.
2. Loosen the cable clamp screw securing the cable to the
engine (Fig. 20).
3. Move the remote throttle control lever forward to the
Fast position.

4. Pull firmly on the throttle cable until the back of the
swivel contacts the stop (Fig. 20).
5. Tighten the cable clamp screw and check the engine
RPM setting:
High Idle: 3150±50
Low Idle: 1750±50
Adjusting the Choke Control
1. Pivot the seat upward and remove the engine shield.
2. Loosen the cable clamp screw securing the cable to the
engine (Fig. 20).
3. Move the remote choke control lever forward to the
Closed position.
4. Pull firmly on the choke cable (Fig. 20) until the choke
butterfly is completely closed; then tighten the cable
clamp screw.
Replacing the Spark Plugs
Replace the spark plugs after every 800 operating hours or
yearly, whichever occurs first.
Type: Champion RC12YC (or equivalent)
Air Gap: 0.030 in. (0.76 mm)
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 that 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 A cracked, fouled, dirty, or otherwise
malfunctioning spark plug must be replaced. Do not
sand-blast, scrape, or clean the electrodes by using a wire
brush because grit may eventually release from the plug
and fall into the cylinder. The result is usually a damaged
engine.
4. Set the air gap between the center and side of the
electrodes at 0.030 in. (0.76 mm) (Fig. 21). 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.
