I checked NADA:

--are the tires in good shape?
--do all the lights work?
--is the battery in good condition? Does starter turn over decently?
--is it free of any cosmetic damage?
--do you have space/time for it? Can it sit around while you sort out the carb issues without being an inconvenience?
--big question: is the carb dissassembled, "in a box"...pieces may be missing...?
