mtgibby Posted July 8, 2018 Report Share Posted July 8, 2018 My Avanti R2 project (2302) came without the carburetor. I have been saving my pennies for a while now, waiting to buy a used Carter afb. So, if you have a tired R1 or R2 carb on the shelf, or have been waiting to replace yours with a nice, new Edlebrock, today's your day! Drop me an email at mtgibby@hotmail.com. Thanks! Mike Next week: I need your R2 aircleaner! Link to comment Share on other sites More sharing options...
brad Posted July 9, 2018 Report Share Posted July 9, 2018 Good luck with that. Last R2 carb I have seen for sale went for over a grand. Link to comment Share on other sites More sharing options...
mfg Posted July 9, 2018 Report Share Posted July 9, 2018 Yes, original Avanti R2 carbs are hard to find...however, there are loads of '60-'67 Carter AFB carbs (GM, Chrysler, etc) for sale on e-bay, and most of these are very similar to the AFB's that Studebaker used....the biggest difference is that some have a side fuel inlet as opposed to the front inlet...no big deal, as the new Edelbrock's also have the side fuel inlet. The question becomes can these older AFB's (or even the new Edelbrock) be calibrated and SEALED to function as a Studebaker Avanti R2 carb would? I've never made this modification, but in reality it seems that doing this wouldn't be all that hard!.......Comments? PS...if an Avanti R3 type air box was used, the carb would no longer have to be sealed! Link to comment Share on other sites More sharing options...
brad Posted July 10, 2018 Report Share Posted July 10, 2018 Sure, I have made a few sealed carburetor from non-sealed ones. There won't be the milled air passage to balance throttle shaft sealing. But that is only important if there is lots of wear. I always brass bush the shafts anyways. The vents can be drilled and tapped for set screws easily, and it has no adverse effects.The accelerator pump seal can be used from an Edelbrock marine carburetor. The idle screws can be partially drilled to fit an "O" ring , and a washer under the spring to compress it. Link to comment Share on other sites More sharing options...
FoLola Posted July 10, 2018 Report Share Posted July 10, 2018 My '63 R2 has the R3 air box. I called Edlebrock for a recommendation of a replacement carb. They advised that since the carb is pressurized the floats in their carbs would collapse. Hmmm... never thought of that. Anyone have an opinion?

brad Posted July 11, 2018 Report Share Posted July 11, 2018 (edited) I solder a brass pin through the floats to prevent collapsing. Edited July 11, 2018 by brad Link to comment Share on other sites More sharing options...
silverstude Posted July 11, 2018 Report Share Posted July 11, 2018 You can drill holes in the brass floats, inject some High Density foam inside and solder the holes shut. Brad's idea is pretty good, so it must work... I had lined up a task of getting a pair of Holley or whoever nitrophyl floats and change the mounting hardware to match the Edelbrock, but never got around to doing it. It's really odd that Edelbrock does NOT make nitrophyl floats... Link to comment Share on other sites More sharing options...
StudeNorm Posted July 12, 2018 Report Share Posted July 12, 2018 When I ordered floats from Daytona I very specifically said they were for a pressurized carb. They replied no problem and sent me a set of floats. I installed them a year ago and now I seem to be having float problems. It will be a week and a bit before I get home to work on this issue but we will see then. Link to comment Share on other sites More sharing options...
