    • A fuel control mechanism for a liquid fuel burner includes a fuel regulating valve which is responsive to flow of liquid fuel through a fuel feed tube for movement between a starting position and a running position. When a fuel control valve for the burner is opened, flow of liquid fuel through the fuel feed tube moves the fuel regulating valve to a starting position in which the fuel regulating valve restricts flow of fuel through a fuel inlet. Air is thereby drawn through an air inlet and mixes with the fuel. After the burner is started and liquid fuel is vaporized within the generator, flow of fuel through the fuel feed tube slows, and the fuel regulating valve falls by virtue of its weight to the running position in which the fuel regulating valve does not restrict flow of fuel through the fuel inlet. Air flow through the air inlet is thereby discontinued, and only liquid fuel flows through the fuel feed tube.
