Engine Maintenance

All the components used to build this engine must

remain in place for the proper operation of this

engine.

CAUTION

Emission Control

Maintenance, replacement or repair of the emission

control devices and systems may be performed by

any non

−

road engine repair establishment or

individual. However, to obtain no charge repairs under

the terms and provisions of the Briggs & Stratton

warranty statement, any service or emission control

part repair or replacement must be performed by a

factory authorized dealer. See the Emission Warranty.

Carburetor Adjustment

Never make unnecessary adjustments to the

carburetor. The carburetor was set at the factory to

operate efficiently under most applications. However,

if adjustments are required, see any Authorized

Husqvarna service dealer for service.

The manufacturer of the equipment on which this

engine is installed specifies top speed at which the

engine will be operated. DO NOT EXCEED this

speed.

CAUTION

Spark Plug

Check the spark plug every 100 hours. Replace the

spark plug if, upon inspection, the electrode (A) is

burned or worn. Make sure that the spark plug is

clean. Check the gap with a wire gauge (B). If

necessary, reset to 0.030 in (0.76 mm). See

(Figure 26).

NOTE:

In some areas, local law requires using a

resistor spark plug to suppress ignition signals. If this

engine was originally equipped with a resistor spark

plug, use same type for replacement.
