Adjustable carburetor made to fit US standard 1bbl manifold bolt patterns. These high quality NEW carburetors feature a fully adjustable external high speed main jet, along with adjustable throttle levers, so you can quickly change the high speed jetting and throttle arm setup. Ideal for fine tuning any application for fuel/air mixture on the high speed circuit, especially when using the carburetors on dual or triple carb installations.

Made from modern Zinc alloy and aluminum castings, and contain ethanol resistant internal parts, to help last longer with modern fuels. We can fit most any automotive or industrial application from the early 1930's up thru present day. All models are manual choke only

This carburetor has been built since 1957, originally for Ford, and have been modified through the years in order to fit a wider range of vehicles.

Works with Ford Load-O-Matic distributors.

Can also be used to replace a Holley 1940, Autolite 1100 and Rochester B carburetors, but may need some re-routing of vacuum and fuel lines.

Autolite 1100 - Watch a video. (ok to use on carbs with or without dashpot)

Holley 1940 - works with Sparkomatic distributor (spark functionality is built into the N1904)

Holley 1920

Carter BBR1 - manual

Carter BBS - will replace but these are manual choke and most BBS are automatic choke, so a choke cable would have to be installed.

Carter RBS - Watch a video.

Rochester Monojet - Can replace the automatic choke type, but you will have to convert to manual choke by adding a choke cable.

For the Mopar slant 6, 1961-1966, we have a different replacement carburetor.

Banjo type inlet - also comes with the standard 1904 fuel inlet so the banjo may not be needed.

UNIVERSAL carburetors are manufactured to the highest quality standards, and contain alcohol resistant parts thru out, for long service life, under normal operating conditions.

Our fully UNIVERSAL carburetors are especially made to allow a wider variety of external adjustments. They have fully adjustable throttle arms, and externally adjustable high speed main jets. This allows the throttle arm to be indexed to any point you may need the arm to move. The externally adjustable main jet allows you to fine tune the high speed rich/lean mixture to the exact demands of your current engine. Variations in fuel lines, vacuum lines, choke cables and air cleaners may require re-routing or adapting of those items. Variations are usually not a problem on standard 1904 carburetors.
