Marvel-Schebler TSX carburetors have the carburetor number on a tag, stamped into the body, or sometimes cast into the float bowl. In some cases, there is no carb number marking. See the Marvel-Schebler TSX Identification Guide for more information.
DLTX and TRX carburetors often have the number cast into the body. Other Marvel-Schebler carbs may have stamped numbers or tags.
