How to Change the Choke Cable on a Harley Davidson Sportster 883
The enrichener (choke) provides essential fuel at start-up. (yellow chopper engine image by Efrain Diaz from

When open, the fuel enrichener (choke) feeds fuel into the float bowl of the carburettor. Air entering the carburettor creates a vacuum that takes the fuel past the enrichener into the throat of the carburettor. The fuel enrichener should open, remain open, and close without binding. A plastic nut next to the enrichener knob controls the sliding resistance of the enrichener control cable (choke cable) within the cable conduit. The enrichener knob is located next to the ignition switch.
