might be worth getting a couple of meters of vacumn line too - you never know if you are going to find a perished one, and its laughably cheap..
also be sure to check ALL fittings are removed from the old carb... when we put ryans carb on, thhe vacumn hard line at the back of the carb just wouldn't mate up, and seemed routed akwardly...
we had alsmost resigned ourselves to the carb being a different thread, when i tthought to check the old one.. sure enough, the line screwed into a fitting, that was screwed into the carb!
