    Anyone out there have any Carter BBD jets available? I need part number 120-297S as listed in my 1966 Service Manual. For a 1966 Dart 270 full resto car. The jets are a "one step lean" as listed in the manual. Hard time finding these, any information would be helpful! 20190804_141639.jpg

      I was looking for jets too. What I ended up doing was buy used carb take jets and drill out to size. Going lean would be an issue
      Good luck

      By the way I had changed my jets to 2 step lean (went from sea level to 5000 feet) bad idea, ran like crap, put standard jets back in.

      If you get down to Fort Collins give me a shout.

        you want to lean them out? Hang a thin piano wire in there. Bigger, just drill 'em with a pin-drill...?

          The jets have matching metering rods, not sure how piano wire would work.

          But that brings up another option to lean things, fatter metering rods, prob won't effect WOT but would effect the rest of the time.

          Just thought of another thing, is your carb a CAP carb? The jetting on those is different still. In 67 120-310s is standard with 120-297s being 2 steps lean ( might be a misprint cause 120-294 is called out to be 1 step lean)

          can you alter the rods? That would be another option. Also check on the rod holder for any adjustabililty, ie. the rod hanger tree on a TQ can be raised or lowered by a screw

          Not a CAP carb, thanks. Standard is 120-294S, according to the book.

          I would need to figure out somehow what size I need. One step lean = what diameter jet? No diameters are listed in the book.
