The Wheeler-Schebler company was formed in 1905, and the Marvel Carburetor Company was established in 1908. Marvel-Schebler Carburetor Co. was formed from the combination of the Marvel and Schebler carburetor companies around 1928; it became a division of Borg Warner Corporation in 1934. Some early models, like the the TRX and DLTX are marked as 'Schebler' only; new models after the mid-1930's are usually marked 'Marvel-Schebler'.
After 1982, some Marvel-Schebler models were produced by Facet Corporation (under the Zenith brand) and from 1990 to 2025 by Zenith Fuel Systems.
Marvel-Schebler carburetors are identified by a number which may be stamped in the body, on a brass tag, or sometimes cast into the body.
Many TSX carburetors aren't marked with carburetor numbers. Since these come in 3 different sizes, the basic carb kit and float can be determined from measuring the screw spacing on the float bowl.
The Carburetor Doctor has kits and floats for most updraft and sidedraft Marvel-Schebler carburetors. We also have throttle shafts and hard parts for many TSX models, and have reproduction TSX carburetors and Zenith replacement carburetors.
