Sierra 18-7013 Carburetor Kit for Tillotson AJ, CO, KA, KB, KC, KD & WB Series Carburetors

The Sierra 18-7013 Carburetor Kit is a complete rebuild kit designed for use in Tillotson AJ, CO, KA, KB, KC, KD, and WB Series carburetors. It is built to restore proper fuel metering and sealing in these carburetors, replacing the gaskets, filter, and needle and seat assembly that wear out over normal use and cause rough idling, flooding, or fuel leaks.

The kit includes a full set of application-specific gaskets along with a fuel filter and a needle and seat assembly, giving a rebuild everything needed in one package rather than sourcing each gasket individually. Components include a carburetor flange gasket (18-2572), a second carburetor flange gasket (18-2571), a fuel filter (18-7832), a carburetor mounting gasket (18-2802), a strainer cover gasket (18-2570), a carburetor bowl gasket (18-2575), a filter cover gasket (18-2569), a strainer cover screw gasket (18-2568), an additional carburetor flange gasket, and a needle and seat assembly (18-7057).

This kit is intended for AJ-53A, AJ-53AT, AJ-54A, AJ-54AT, AJ-55AO, and AJ-55AT carburetors, as well as KA, KB, KC, and KD series carburetors. Each Sierra product meets or exceeds the original equipment part it replaces, and buyers should check their carburetor model number before ordering to confirm a correct fit.
