Thanks all! I never did find any detailed specs. And I am sure they are out there somewhere but not readily discoverable on the net right now.


To answer why I want them, I have overhauled a fair number of carbs of this era. Many of them I got off ebay as cores and some were in bad condition. Most of these were pre-war Carters. The documentation on Carters is pretty complete and included the sizes of various orifices, idle tubes, etc. I found that even with thorough cleaning (carb cleaner soak followed by ultrasonic, small brush and pegwood to remove the stubborn dirt) there were still hardened deposits that reduced diameters by sometimes significant amounts, especially on the very small ones, like 68 drill or smaller.


Doing a light ream with the proper drill will remove these deposits and hopefully gets them back to what was intended by the designers. Obviously I am not removing metal. Once I started doing this I noticed that my results were more reliable and uniform. This is just my experience but YMMV.
