Joe Johnston just told me about a place in Washington called Carbs Unlimited that specializes in carbs and carb parts. He just ordered some small parts for his Babybird from them and was pleased with their service. So I called that company, talked with the owner, and asked if I could add him to our Advertisements Forum, and he agreed to that and I added them. So when looking for carb parts, you might give them a try. They might have what you are looking for. They list Holley's, Carter's, Motorcraft, and Motorcraft 4100's that they have parts for. Check out their Parts section.
