This kit is used to rebuild or overhaul 1 barrel Stromberg BXOV-BXVD-BXUV carburetors. Stromberg OEM #s included in this kit are 1939-1952 Studebaker 6 cylinder engines. We replenish our kits on a frequent basis so you do not need to worry about receiving a kit that has been sitting on a shelf for years drying out the component parts & gaskets.
