Very nice car. Much better than my 250C. Carbs can have air leaks from over tightening the screws and warping form heat. Make sure all the carb surfaces fit well.

Get an air volume meter. I don't know why I spent so much time listening to carbs instead of getting a meter. If nothing stupid has been done to the carbs they should be fine. Don't expect great fuel mileage. If worse come to worse, get a Weber kit ~$1000.
