Overview of Demon Carb Rebuild Kits
Demon carburetor rebuild kits provide all the necessary components to thoroughly rebuild Demon 4-barrel carburetors. Available for the Speed Demon, Mighty Demon, Road Demon, and Race Demon, these kits replace worn parts for peak performance.
Purpose of a Rebuild
Over time, gaskets dry out, needles and seats wear, and jets clog—a rebuild restores your carb to original factory specifications for maximum power.
Matching the Kit to Your Carb
Demon offers application-specific rebuild kits tailored for each carburetor model. Ensure you order the proper kit for your exact carb.
Key Components in a Rebuild Kit
Kits include all the common failure parts you’ll need:
Gaskets and Seals
New base, throttle body, and fuel bowl gaskets prevent vacuum leaks. Viton bowl seals resist modern fuel blends.
Needles and Seats
New precision-machined needles and seats ensure accurate fuel control under pressure. Resists flooding and leaks.
Diaphragms
Heat-resistant diaphragms restore consistent accelerator pump operation. Viton composition withstands alcohol fuels.
Power Valves
Replaceable power valves in multiple spring ratings help fine-tune fuel flow for your engine’s needs.
Jets, Bleeds and Emulsion Plates
New jets, air bleeds, and changeable emulsion plates support ideal fuel calibration.
