Hi Utah and Mikey.
Here is a thread with various pictures of my Carter YF rebuild and questions and answers along the way. Pages 1-5 are discussions about my carburetor's symptoms, discovery that it was a Frankencarter, etc. From page 6 on is the actual core I bought from carbking and my subsequent rebuild of it.
Rebuilding the carburetor was actually the most satisfying and fun task that I completed on Ol' Roy.
