A.S.E.C.C. Engine Data


Carburetor Identification for
Early Briggs & Stratton Engines

Colorbar


This document pictures many of the carburetors used on Briggs & Stratton engines up until about 1950 and the engine models where they were used. There were some variations on these carburetors and many of the engines used more than one type. Hopefully this listing will take care of most circumstances. The Carburetor type numbers are arbitrary and are for differentiation only.

You can browse through the pictures or click on the Briggs & Stratton Model letter in the table below to go to the most common carburetor for that engine.
