the filter and squeeze the filter to spread and 
remove excess oil.

cover into the slots at the right side of the air filter 
housing. 

Swing the cover to the left until the tab on the air 
filter cover snaps into place in the slot.

Carburetor Adjustment

If the engine will not idle, hesitates or stalls on 
acceleration, or there is a loss of engine power have the 
carburetor adjusted by an authorized service dealer.

Replacing The Spark Plug

The spark plug should be removed and check after 
every 50 hours of operation. To replace the spark plug 
proceed as follows:

Stop the engine and allow it to cool. Grasp the plug 
wire firmly and pull the cap from the spark plug.

Clean dirt from around the spark plug and remove 
the spark plug from the cylinder head by turning 
counterclockwise using a socket.

Set the air gap at 0.025 in (0.655 mm.) using a 
feeler gauge. See Figure 10.

Figure 10

Install a correctly gapped spark plug in the cylinder 
head and tighten by turning the socket clockwise 
until snug. Do not over tighten.

Spark Arrestor Maintenance

Remove the muffler cover by pressing down on the 
corner with a flat blade screwdriver. Slide the 
notches on the sides of the muffler cover over the 
tabs on the engine cover and remove.

Remove the screw attaching the spark arrestor 
cover to the muffler. See Figure 11.

Figure 11

Pull the tab on the spark arrestor cover out of the 
muffler and remove the spark arrestor cover.

Remove the spark arrestor screen from the spark

replace screen.

Reinstall the spark arrester screen, spark arrestor 
cover, and screw.
