Abstract:
1. A carburetor comprising: a housing provided with an intake channel section; a throttle element arranged in the intake channel section and adjustable between a closed throttle position in which a flow cross-section of the intake channel is substantially closed and an open throttle position in which the flow cross-section of the intake channel is substantially released; a choke element arranged in the intake channel section and adjustable between a closed choke position in which a flow cross-section of the intake channel is substantially closed and an open choke position in which the flow cross-section of the intake channel is substantially released, wherein the choke element has at least one start position in which the choke element at least partially closes the flow cross-section of the intake channel; a coupling device coupling a position of the throttle element in a start position to a position of the choke element when the choke element is in the start position; wherein the choke element has an enriching position; wherein the coupling device has an actuator that moves the choke element into the enriching position when the throttle element is moved, starting from the start position of the throttle element and the start position of the choke element, in a direction toward the open throttle position of the throttle element.
