In other threads, folks have mentioned Benchwick Carburetor in Youngstown, Ohio as a source for carb rebuilds. Fortunately, I live about an hour away so I took the Darrin unit to them today. Housed in a former gas station, when I pulled in this afternoon, the proprietor was fine tuning the carb on a 41 Packard. He took one look at my carburetor and knew it was a Willys unit and said he'd have it ready in a few days. Apparently, a couple of hemi carbs were in for service so they're first in line.
