The JET PERFORMANCE Rochester 2G Carb Rebuild Kit (MPN 201005) is a complete gasket and seal set for anyone refreshing a tired Rochester 2G two-barrel carburetor. It targets the worn parts that cause hard starts, rough idle, and fuel seepage on these carburetors found across GM applications from the mid-1960s through the early 1980s. If you're chasing a flooded float bowl, a stumbling accelerator pump, or a vacuum leak at the throttle body, this rochester 2 barrel carburetor rebuild kit covers the consumables you need to bring the carb back to spec. It's a straightforward job for a weekend mechanic.
The kit includes the full gasket lineup for a proper 2G rebuild: air cleaner gasket, fuel inlet gasket, venturi cluster gasket, throttle body gasket, bowl cover gasket, flange gasket, power valve gasket, and pump discharge nozzle gasket. It also ships with an accelerator pump cup to restore crisp throttle response and two needle sizes so you can dial in the correct fuel inlet seal for your application. Pairing the new pump cup against fresh gaskets keeps fuel where it belongs and eliminates the metering leaks that plague decades-old carburetors. Before reassembly, many builders replace the brass float and inspect the needle and seat at the same time, since those wear items work directly with this kit to set float level and stop bowl flooding.
Reach for this kit when a 2G has sat for years, runs rich, or weeps fuel after shutdown. A full gasket swap is the right move any time you have the carb apart on the bench, and it pairs well with a fresh power valve and a verified float level for a clean rebuild. Browse our wider air and fuel selection for the supporting parts that round out the job, including replacement needle and seat sets and matching power valves. Keep the install video and a factory tuning chart handy, set your idle and mixture screws after warm-up, and the carb will deliver consistent fuel metering for years.
It comes with a full gasket set covering the air cleaner, fuel inlet, venturi cluster, throttle body, bowl cover, flange, power valve, and pump discharge nozzle. It also includes an accelerator pump cup and two needle sizes so you can match the correct fuel inlet seal to your carburetor.
This kit is built for the Rochester 2G two-barrel carburetor used across many GM applications from the mid-1960s through the early 1980s. Confirm your carburetor is a 2G family unit before ordering, since 2GC and 2GV variants can use different parts.
No. The kit supplies the gaskets, accelerator pump cup, and two needle sizes. If your float is damaged or the seat is worn, you'll want to source those separately. We stock replacement floats and needle and seat sets in our air and fuel category.
Yes. A 2G rebuild with this kit is a common weekend project. Disassemble the carb, clean every passage, replace each gasket and the pump cup, set the float level, then reassemble. Set idle and mixture after the engine reaches operating temperature.
