Carburetor Adjustment
These engines are equipped with a diaphragm-type
carburetor. The carburetor has been carefully cali-
brated at the factory. In most cases, no further adjust-
ment will be required.
WARNING:
Electrical Shock!
Never touch electrical wires or components while the
engine is running. They can be sources of electrical
shock.
The condition of the air filter is very important to the op-
eration of the trimmer. A dirty air filter will restrict the
air flow to the carburetor. This in turn upsets the fuel-
air mixture in the carburetor. The resulting symptoms
are often mistaken for an out-of-adjustment carburetor.
Therefore, check the condition of the air filter before
adjusting the carburetor. Refer to “Air Filter” Serv-
ice/Maintenance Instructions.
1.
Before removing the spark plug, clean the area

if necessary. Replace the plug if it is badly burnt or
if reuse is questionable.
