The needle valve or flow valve controls the flow of gas into the Bunsen Burner.
A needle valve is a type of valve having a small orifice and a threaded, needle-like plunger. It allows precise regulation of flow, although it is generally used for, and is capable of, only relatively small flow rates.

That is the main jet needle valve.
The needle valve controls the flow of gas into the Bunsen burner, regulating the size and intensity of the flame. By adjusting the needle valve, you can increase or decrease the amount of gas entering the burner, which in turn alters the flame's temperature and size.
A plug valve controls flow using a cylindrical or conically tapered plug, providing quick open and close operation. A needle valve controls flow with a long, tapered needle that fits into a seat, allowing for precise flow regulation in applications requiring fine adjustments.
I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high. I would replace the needle valve and seat and check float level.I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high.

It is in the float chamber of the carburetor.
Adjusting the gas needle valve controls the flow rate of gas entering the burner. Decreasing the gas flow by turning the needle valve counterclockwise results in a smaller, bluer flame with less heat, while increasing the gas flow by turning the needle valve clockwise produces a larger, yellower flame with more heat.
Adjusting the needle valve on the Bunsen burner controls the amount of air mixed with the gas. Opening the valve increases air, resulting in a blue, hotter, more oxygen-rich flame. Closing the valve reduces air, creating a yellow, cooler, more fuel-rich flame.
A needle valve on a Bunsen burner is used to control the flow of gas, allowing for precise regulation of the flame's size and intensity. By adjusting the needle valve, the user can fine-tune the amount of gas being released, which directly impacts the flame's temperature and stability. This control is essential for achieving different heating applications in laboratory settings.
Never ever use a Gate type of valve for throttling ONLY a globe pattern is designed for this purpose and a needle valve
1 1/4 turn out.
