Braswell Carburetion
Since 1969 Braswell Carburetion has been dedicated to providing the highest quality carburetors and components to engine builders, carburetor shops, and motorsport competitors. While some companies build everything the same, Braswell custom builds all of its carburetors and components to suit the needs of the specific application. We offer complete carburetors, carburetor kits to authorized builders, rebuild kits, gaskets, tuning components, spacers, shear plates, jets, and air bleeds. Pretty much everything needed to build or tune race winning carburetors.
