Gas burner assembly for a cooktop appliance

A cooking appliance comprising:

• a cabinet comprising a cooking chamber;
• a cooktop positioned above the cooking chamber;
• and
• a gas burner positioned within the cooktop, the gas burner defining an axial direction, a radial direction, and a circumferential direction, the gas burner comprising:
• a base extending along the radial direction and the circumferential direction, the base defining a mixture inlet therethrough along the axial direction;
• an outer wall extending from the base along the axial direction, the outer wall and the base collectively forming a fuel chamber;
• a plurality of flame ports defined within the outer wall, the fuel chamber being in fluid communication with the plurality of flame ports;
• a simmer flame chamber positioned at the outer wall radially outward from the mixture inlet;
• a conduit formed between the simmer flame chamber and the mixture inlet, the conduit extending along the radial direction and defining a conduit inlet proximate the mixture inlet and a conduit outlet proximate the simmer flame chamber, the conduit comprising:
• a first wall extending along the radial direction from the mixture inlet to the outer wall, wherein a first conduit inlet of the conduit inlet is formed through the first wall along the circumferential direction;
• a second wall extending along the radial direction from the mixture inlet to the outer wall, the second wall being predominantly parallel with the first wall, wherein a second conduit inlet of the conduit inlet is formed through the second wall along the circumferential direction;
• a first section extending outward in the radial direction from the first conduit inlet or the second conduit inlet at a first vertical height;
• and
• a second section extending outward in the radial direction from a distal end of the first section at a second vertical height, the second vertical height being below the first vertical height;
• and
• a fuel supply system positioned proximate the mixture inlet.
