My 75 Duster with a 318 and three speed manual transmission came with a Carter BBD 8000S carburetor. Does anyone know what would be different about a Carter BBD 8001S? The description says it’s for a 1975 318.

Thanks for the information. I was afraid that might be the case but was hoping it wasn’t.

there is nothing to stop you taking the rods jets and little jet spring from one and putting them in the other....
the wrong carb with a decent base, none leaking throttle shaft and a bit of linkage you don't need will still work better than a worn one, just configure its jetting as per the orginal.
block off any extra vacuum connections you don't need.
warped air horn and worn out base/throttle shaft bush area is usually the BBD problem.
or missing parts.......like the clip for the fuel bowl vent.... necessary on the older style for them to be RIGHT..
.... yours will have a tin top if its 1970s, and this won't be a problem for you, accelerator pump rod through the side, rather than a slide through the top of the bowl.
You can get the linkages cut off, the throttle removed the holes bushed and it all reassembled, with the linkage welded back, if this is the problem with your old one.

Thanks for taking the time to write all of that out. It's an interesting option. The 8001S carb that's available is new old stock and listed at $399, which isn't cheap, but I'd be willing to spend it if it was suitable to use as is. At the listed price I doubt it will sell quickly, so I think I have some time to consider your suggestion. For obvious reasons a suitable 8000S would be the preferred option. I missed a new old stock one that came up on eBay by about a week awhile back so now I'm doing a daily search and hoping to get lucky.there is nothing to stop you taking the rods jets and little jet spring from one and putting them in the other....

thats a lot of money for a BBD you might find you can get yours professionally rebuilt for less than that.
really depends if you just want a nice new one, or you have a problem with the old one...

That's it right there. This car's been following me around since I was seventeen back in 81. I figure I owe it a little extra for staying with me for so long.
