Abstract
A manually guided implement having a motor unit and a tool unit driven by the motor unit. The motor unit includes an internal combustion engine having a carburetor, and a butterfly valve. A throttle acts upon the butterfly valve via a transfer mechanism. A speed regulator is provided for the internal combustion engine. The transfer mechanism is divided into two transfer portions. The speed regulator is a mechanical speed regulator and is disposed between two transfer portions such that the throttle, via the first transfer portion associated therewith, as well as the speed regulator together act upon the second transfer portion, which is associated with the butterfly valve, whereby as its speed increases, the speed regulator effects a closing of the butterfly valve.
