Rebuild your Rochester four-barrel and restore proper fuel metering with the Walker Products Carburetor Repair Kit 151032A. It's built for the Rochester 4 BBL, 4MV carburetor and drops in as a direct-fit rebuild kit for a wide list of 1966-1974 GM applications, including the Pontiac Catalina, Firebird and Grand Prix, Buick Electra and Riviera, Chevrolet Impala, Camaro and Chevelle, GMC and Chevrolet C/K pickups, and many more — see the Buyer's Guide tab for the full list.
- OE-matched contents: gaskets, seals, and parts sized to support proper fuel metering and fit.
- Complete rebuild: includes the gaskets, seals, jets, needles, and other wear components used to rebuild the carburetor to OE specifications.
- Ethanol-ready: engineered for use with today's fuel blends, including ethanol-containing fuels.
Carburetors accumulate wear on their gaskets, seals, and metering parts over time, which can lead to rough idle, hard starting, fuel leaks, or poor fuel economy. If a worn or leaking carburetor is the cause, installing this kit replaces those degraded components to help restore proper fuel flow, throttle response, and idle performance — a cost-effective alternative to replacing the entire carburetor.
