Rebuild your Rochester four-barrel and restore smooth fuel delivery with the Walker Products Carburetor Repair Kit 151056A. This kit is designed for Rochester 4 BBL carburetors — models M4MC, M4ME, and M4MED — used on 1985-1989 Chevrolet and GMC trucks, vans, and SUVs, including the Astro, C10/C20/C30, K10/K20/K30, Suburban, El Camino, and G-series vans, with the V6-4.3L, V8-5.0L, V8-5.7L, and V8-7.4L engines.

- Confirmed kit contents: includes the needle, seat, and flange to renew key fuel-metering and sealing points inside a four-barrel carburetor.
- Ethanol-ready: engineered for use with today's fuel blends, including ethanol-containing fuels.
- OE-level quality: Walker components are built to meet or exceed original-equipment specifications.
- Not included: float, accelerator pump, inlet gasket, and throttle linkage clip are not part of this kit — source them separately if your rebuild needs them.
Rough idle, hard starting, fuel leaks, and poor fuel economy can be signs that carburetor wear components have degraded. If a worn carburetor is the cause, installing this kit replaces those wear parts to help restore proper fuel flow and idle behavior. Country of origin: United States.
