The problem with old carbs is that you have to know what car they fit to sell them on ebay. Maybe the books that go with them will help identify them and their applications. If so it's a good deal. I would plan on two hours to rebuild the 1V or 2v carbs not counting cleaning and testing. after you've been doing it a while you could get it down to about one hour each. Let me know how it goes. I might be interested if you pass on the deal.
