Jim:
For '55 teapots there are three possible carbs used. All three are jetted differently. Also, the altitude of the intended location of the car makes a difference. What are the letters stamped in the back of the carb, such as ECJ or ECK, and a suffix letter? All will have a 9510 stamped between the prefix and suffix letters.
