I'd like to try to rebuild the carb before spring rolls around again. Any suggestions on the best rebuild kit? | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | Put a link to a photo of it & the fellow Stovebolters will ID it & tell were the numbers should be on it. The best source for a kit is your local Carquest or Napa store. The carb specialty shops have them or the specialty parts stores. If it is a W-1 Carter it will have to come from a specialty store.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | | | | Joined: Sep 2010 Posts: 695 Shop Shark | | Shop Shark Joined: Sep 2010 Posts: 695 | Have you looked it over closely for a brand name?
I have several and though I couldn't tell you what specific year they were from, they all have the brand name cast onto the lower casting area.
Some, it took a wire brush to remove the dirt and grime to reveal.
Just a thought...

Hygrade 123A should be the right kit and the best place for all mechanical parts in our area is:

I appreciate the help. | | | | | Joined: Mar 2005 Posts: 1,513 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 1,513 | Here’s the maintenance booklet for 1951 Rochester model B carburetors. When you have the air horn off check it against a flat surface for straightness. If the carb leaks or weeps people tend to tighten the air horn screws which in turn makes it warp/leak even more. At some point the air horn was redesigned to add more rigidity and if you ever purchase a rebuilt one (Autoline remanufactures these carbs) it will likely be the later design and have less likelihood of leaking.

Recently came across a few videos on Youtube (thanks to the Stovebolt!) of a Rochester model B being rebuilt. There are 3, each is 8 - 9 minutes long, and they're pretty helpful. Search "Rochester B rebuild" on youtube and they'll come right up.
