Carburetor assembly start setting detection arrangement

A carburetor assembly comprising:

• a control unit,
• an air channel,
• a throttle valve,
• a choke valve,
• a pulsed fuel valve,
• a fuel supply line running between the pulsed fuel valve and a fuel outlet that is arranged to supply fuel to air running in the air channel, and
• a rotation angle detector assembly,
• wherein the control unit is adapted to control the fuel valve to supply fuel in accordance with a certain start setting,
• wherein the choke valve is configured to be open or closed in said certain start setting,
• wherein the rotation angle detector assembly comprises:
• a throttle detector part that is at least indirectly mounted to a throttle shaft that is connected to the throttle valve such that the throttle detector part is arranged to rotate together with the throttle valve,
• a choke detector part that is at least indirectly 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, and
• a sensor device that is connected to the control unit and is adapted configured to be affected by the throttle detector part and 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 and an opening degree of the throttle valve.
