A carburetor for an internal combustion engine includes an intake channel section ( 2 ) as well as a throttle element journalled in the intake channel section ( 2 ). The throttle element is adjustable between a full-load position ( 25 ) and an idle position ( 26 ). A pump ( 20, 30 ) is provided for additional fuel metering and this pump includes a pumping chamber ( 24, 34 ) and a pump piston ( 21, 31 ) guided in the pumping chamber ( 24, 34 ). The position of the pump piston ( 21, 31 ) is coupled to the position of the throttle element. To ensure an optimal supply of the internal combustion engine with fuel in each operating state, the pump piston ( 21, 31 ) is so coupled to the throttle element that fuel is pumped from the pumping chamber ( 24, 34 ) into the intake channel section ( 2 ) when there is a displacement of the throttle element from the full throttle position ( 25 ) into the idle position ( 26 ).
