Abstract

The invention is directed to an adjusting device for a throttle pull of an internal combustion engine for a portable handheld work apparatus. A pull wire (11) of the throttle pull acts on the carburetor (4) of the engine. The carburetor (4) is attached to the inlet of the engine with a spacer (6) disposed therebetween. A tension piece (5) of the adjusting device is pivotally journalled on the spacer (6) by a bolt. The pull wire (11) lies with a segment thereof on the outwardly pivotable arm of the tension piece (5). The position of the tension piece can be adjusted with the adjusting screw (14). The adjusting screw can be screwed out of the pivot arm axially in the direction toward a support. The tension piece (5) is configured as one piece with the bolt (12) and is securely held with a form-tight holding arrangement in the axial direction of the bolt (12). The adjusting device is cost-effective and provides for a reliable and precise adjustment.
