Motorcraft 2100 2 Barrel Rebuild

Disassemble your carburetor. Take a lot of pictures as you go along in case you have questions.
Consider not taking the throttle shaft apart unless you are equipped to drill and tap broken screws.
Soak your carburetor parts in any 1 gallon carburetor clean found at your favorite parts store. Follow the directions. Over soaking can damage the metal on your carburetor.
