A carburetion assembly including flow control means is provided for controlling a discharge spray angle of a fuel and air mixture thereof. According to one embodiment of the present invention, the flow control means can comprise a plurality of circumferentially spaced apertures in a shroud member which are effective for providing a control portion of compressor airflow in a downstream, axial direction from a swirler stage of the swirler assembly. The apertures provide a predetermined amount of airflow circumferentially about the fuel and air mixture for constraining the mixture and controlling the discharge spray angle thereof.
