Engine Maintenance

CAUTION

All the components used to build this engine must remain in place for the proper operation of this engine.

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.

CAUTION

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.

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.
