I was able to order the rebuild kit!  I contacted The Carburetor Shop LLC out of Eldon, Missouri, and they were very helpful in getting me the rebuild kit I needed for Cornelia.  As I mentioned in my earlier post, however; without knowing the specific model number of the carb, I would have gotten nowhere.

I also talked to them about the potential impacts of ethanol fuel.  They stated that they use leather accelerator diaphrams for their accelerator pumps, so they will be impervious to the detrimental effects of ethanol, which will degrade rubber.  They also have some additional information on adjusting your carburetor for using ethanol blended fuels, which I intend to read over very carefully.

I've updated Cornelia's Start-Up list accordingly.  We're on our way :-)
