CK410 Carburetor Master Repair Kit for Holley 2140-4000 Teapot 'Concentric' Carburetors

Holley 2140/4000 'Teapot' carburetor repair kit includes:
ethanol-resistant Viton accelerator pump cup
both styles of needle/seat that were used interchangeably in production
correct felt material for float bowl seal
secondary diaphragm
idle mixture screws and springs
power valve actuator
spark delay valve
acclerator pump discharge needle
float spring
correct seals and gaskets

Please note that most of the jobber kits available elsewhere have serious problems that make a successful rebuild very difficult. Cheaper kits have a rubber seal, instead of the OEM felt, making assembly of the float bowl onto the choke housing nearly impossible. Also, the o-rings and retainer rings are mostly the wrong size. As well, the pressed in inlet seat isn't included and the gaskets are cut incorrectly.
These issues have all been addressed in our kit, along with the addition of parts not found elsewhere, including the float bumper spring, which is often rusted out, as well as both sizes of pump cup found in early and late production carbs.

Made in USA. Ethanol compatible. Includes instructions.
