The excess fuel device has the operating position and at least one start position. The working tool has a return device switching the excess fuel device from the start position to the operating position, if the crankshaft rotation speed exceeds the return frequency. The return device blocks switching the excess fuel device to the start position at a rotation speed higher than the return frequency.
EFFECT: simplicity of the working tool design, excluding errors in control.
