  • R2 Carb Floats

    This being the first R2 carb I've taken down, I was struck by the difference in the floats in the carb and the replacements. The old floats have formed stiffeners in the sides making them noticeably stronger in terms of resisting bending by finger squeeze. My question is, are these the original floats and are they still available?

    I have taken many original AFBs apart- and they all have the "windowed" float.

      Thanks for the info. Are the windowed floats still available as a part separate from the rebuild kits?

        Check with Ted Harbit, I think he fills the floats with foam or something so he can run 20 PSI boost.

          The R 2 floats have an aluminum "x" inside them to help keep them from collapsing under boost. I've found the standard floats (either window or smooth) will hold up pretty well as long as the boost stays under about 10 pounds.

          If you have a problem, you can drill a small hole in each end of the float and fill them with foam and solder the holes shut after the foam dries. The foam will ooze out the holes and can be trimmed before soldering the holes shut.

          I found floats from a Toyota pick up truck that were nitrophyl and modified the hanger to fit the AFB and use them in the '51. So far, with 20 pounds boost, no problem.

            I had already filled a set of floats with foam in prep for this project, but didn't know the R2 floats were already reinforced. The originals seem stiffer than the filled floats. Of course, the foam support probably doesn't give up as catastophically when it does give up.

            To be prepared, I'll try to have both available.

              You also may wish to look at this site. They do address some of the r2 afb stuff. In addition, there may not be any need to use brass floats, unless you will be exceeding factory boost specs.

                Jim,
                If those are the floats from "our" R-2, I'm sure they are the originals. I am the only one who has ever touched them, and rebuilt a standard AFB at the same time for comparison. I used the AFB in the turbostude, and did in fact manage to crush them with 21 pounds boost. The hot setup for me turned out to be thermoquad floats grafted on to the brackets of a standard set.....

                  Yes, they are Greg. Carter did a few "tricks" compared to the AFB, didn't they? I found a lot of changes, some subtle, some obvious. Learned a lot, and I can't wait to start tuning it with the wideband.
