There are "steps" on the choke cam that pull the gas pedal up to a high speed idle when the choke is on. If you don't step on the gas pedal once before starting, the carburator/choke assembly cannot function properly.
It is a carburetor where the engine coolant is routed through the choke system of the carburetor. When the coolant is cold the choke will close. As the engine coolant heats up it opens the choke.
The carburetor choke closes by using a bimetallic spring or an electric actuator that responds to engine temperature. When the engine is cold, the choke valve is partially closed to restrict airflow, enriching the fuel mixture for easier starting. As the engine warms up, the bimetallic spring or actuator gradually opens the choke valve, allowing more air to mix with the fuel for optimal combustion. This process is crucial for maintaining engine performance during different temperature conditions.
That part is called a bimetalic spring with housing the purpose of this part is to coil up in cold temperature and uncoil when heated, that cause the choke blade to open and close.

Check the choke throttle and linkage for binding that won't allow the choke baffle to close partially when you let off the gas. A good carburetor cleaner will dislodge any gunk or goop - follow the instructions on the can.
The choke on your lawnmower may not close due to a few common issues, such as a stuck or damaged choke cable, which can prevent it from returning to its resting position. Dirt or debris in the choke mechanism can also impede its movement. Additionally, worn or broken springs that help the choke close may contribute to the problem. Regular maintenance and cleaning can help resolve these issues.
The choke light on a 1984 Chevy El Camino will come on if the choke fails to open or close. The choke should be visually inspected to verify functionality.
You need to take you car to a mechanic. It is obvious you do not know what you are doing. Your battery is in the electrical system. Your choke is in the fuel system. They are separate. It is normal to pull out your choke to start your engine. It is not normal to have your choke out to run your engine. As soon as your engine starts, you should push your choke in. When you pull out your choke, you close the air going into your carb. Then you push in the choke to allow air to flow through your carb. That lets you speed up or slow down. If it won't run with the choke pushed in, try pushing the choke in slower.
The choke spreads fairly quickly and is use for upland hunting such as: quail, rabbits and close range game.
