Associated Comments:

• Notice - Due to the natural color variations of the dichromate plating process, the plating color may vary from casting to casting (within a carburetor) and from carburetor to carburetor. This is considered normal and is not a cosmetic defect.
• If you desire a carburetor with no color variation, please shop our black and shiny finish carburetors.
