Hey all, Happy 4th.
I’m going to need to rebuild my carburetor. It’s been sitting in a dirty climate for untold years.
How can I ID the carburetor? I know it’s a Rochester because it says so. How can I I’d the model to buy a rebuild kit for it?
It’s on a 1953 Chevy 6500 with a 261 manual transmission.
Is there any difference between the 216-235-261 carb size?
Thank you for the help in advance

Is there any difference between the 216-235-261 carb size?
Yes, venturi, throttle disc and flange pattern.

Thanks for the help panic.

If your carburetor has been sitting a long time, you might get lucky, and the carb still have the original triangular tag.

The 216 has a 2 11/16 center to center mounting flange
The 235 and 261 both have 2 15/16 center to center mounting flange, but the 261 has a larger throttle bore, and a larger internal venturi.

Additionally, there are differ style accelerator pumps (round, flat) different jets, different power valve, and different gaskets.

Summarizing, we make 86 DIFFERENT carburetor rebuilding kits for the various Rochester B, BC, and BV carburetors.
