What happens when you turn off the choke on an engine?

How does a choke plate work on a carburetor?
When closed, the choke plate restricts most of the incoming air from entering the carburetor’s venturi. This creates additional low pressure in the venturi and also forces air to be drawn through a port on the front of the carburetor body. This port leads to the air space at the top of the bowl.
The choke increases the amount of fuel in the mixture, creating a richer mixture. This allows the engine to function at its best until it has warmed up enough to run on its normal operating fuel mixture. At that point the choke is turned off and the engine runs with a leaner fuel/air mixture.
