REBUILDING

A: The 2100 is a two-barrel downdraft carburetor widely used by Ford and AMC on V8 engines from the late 1950s through the 1970s. Known for its simplicity, reliability, and ease of service, it remains a popular carburetor for classic car restorations.

Q: What is the best way to disassemble the 2100 carburetor?

A: Take plenty of photos during disassembly to aid in reassembly. Use a cookie sheet to keep parts from rolling away. Avoid removing the throttle shaft, throttle valves, or choke shaft unless absolutely necessary, as these are difficult to reassemble correctly.

Q: Are there any special tips for cleaning the 2100 carburetor?

A: Disassemble the carburetor fully (except for rubber and electrical parts), soak metal components in Simple Green for two hours, then rinse with hot water. Blow out all passages with compressed air, ensuring small holes are clear. Soda blasting can also help with stubborn deposits. If corrosion is severe, replacement may be necessary.

Q: Should I use sealant on the gaskets?

A: No, do NOT use any gasket sealant, as gasoline can break down the sealant and clog the carburetor’s small passages. Always install gaskets dry.

Q: How do I test the float for leaks?

A: For brass floats, immerse in hot water and watch for air bubbles (which indicate leaks). For plastic or nitrophyl floats, weigh them and compare the weight to the specification. Replace if out of spec.
