Based on phisic , the size of Needle Valve is limited , maximum 1" and used for high pressure operation , Plug Valve the size no limited
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.

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 Bunsen burner consists of a base, a barrel or tube, an air vent, a collar, and a needle valve. The base usually has a gas inlet for connecting to a gas source, while the barrel is where the gas mixes with air for combustion. The collar and needle valve control the amount of air and gas entering the burner, regulating the flame produced.
The clear plastic section of the needle is called the needle hub. It is the part of the needle that attaches to the syringe and holds the needle in place.
A small, thin needle called a butterfly needle or a catheter needle is commonly used for chemotherapy. These needles are designed to be gentle on veins and can accommodate the flow of chemotherapy drugs.
A plug valave uses a cilindrical kind of element to shut down the flow. The ball valve uses a spherical element to sut down the flow
The needle valve or flow valve controls the flow of gas into the Bunsen Burner.

That is the main jet needle valve.
General procedure: (1) ensure spark plug is clean and fresh fuel in fuel tank; (2) close needle valve (clockwise) until it seats - do not force; (3) open needle valve (counter-clockwise) 1 to 1-1/2 turns; (4) start engine and let warm up for about five minutes; (5) close needle valve (clockwise) slowly until engine starts to stall then open neede valve (counter-clockwise) slowly until engine starts to stall; (6) set needle valve midway between the two points.
Plug valves are valves with cylindrical or conically-tapered "plugs" which can be rotated inside the valve body to control flow through the valve. There are two types of plug valves - one has a port through a cylindrical plug and the other is the eccentric plug 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.
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.

i guess the answer is the valve plug
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.
