To remove a carburetor, start by disconnecting fuel and vacuum lines from the carburetor assembly. In some engines, the carburetor is located directly under the air cleaner, you may have to remove this to gain access to the carburetor. Place a small can or rags beneath the carburetor to catch the gas that leaks out of the line. Hang gas-soaked rags to dry out on the open, as these can be flammable.
Disconnect the connections to the throttle, making sure to memorize which holes the connections go. To be accurate, take a photo before removal.
Unscrew the carburetor assembly from the intake manifold. Take note of how the carburetor attaches to the manifold and how the gaskets are installed. Take pictures if necessary. Do not try to partially disassemble the carburetor until it is completely out of the car and on top of a clean work area. Once the carburetor is fully removed, cover the intake manifold with a clean towel or rag to prevent small parts from falling into the manifold.
Photograph or film the carburetor from all angles before you disassemble it to help with the reassembly later. You may also film the carburetor during the disassembly. Many parts inside the carburetor look the same, but they are not interchangeable. Keep track of where each part goes as you disassemble it. When it's time to reassemble the carburetor, refer to the photos to ensure accuracy.
