Carburetor

Your Husqvarna product has been designed and manufactured to specifications that re- duce harmful emissions. After the engine has used 8--10 tanks of fuel, the engine will be run--in. To ensure that it continues to run at peak performance and to minimize harm- ful exhaust emissions after the run--in peri- od, ask your servicing dealer to adjust your carburetor.

WARNING: The complete clutch, clutch cover, and shaft must be fitted before the machine is started, otherwise parts could come loose and cause personal injury.

Function

SThe carburetor governs the engine’s speed via the throttle control. Air and fuel

are mixed in the carburetor.

SThe T--screw regulates the throttle setting at idle speed. If the T--screw is turned clockwise this gives a higher idle speed; turning it counterclockwise gives a lower idle speed.

Basic setting

SThe basic carburetor settings are ad- justed during testing at the factory. Fine adjustment should be carried out by a skilled technician.
