The present disclosure relates to a carburetor assembly () comprising a control unit (), an air channel (), a throttle valve (), a choke valve (), a pulsed fuel valve (), and a fuel supply line (). The control unit () is adapted to control the fuel valve () to supply fuel in accordance with a certain start setting, where the choke valve () can be open or closed. The carburetor assembly () comprises a rotation angle detector assembly () with a choke detector part () that is mounted to a choke shaft () that is connected to the choke valve () such that the choke detector part () is arranged to rotate together with the choke valve (). The rotation angle detector assembly () further comprises a choke sensor device () that is connected to the control unit () and can be affected by the choke detector part () such that the choke sensor device () provides different output signals to the control unit () in dependence of whether the choke valve () is open or closed.
