Hey! New here, noob question so go easy . I am working on a 69 mustang but dont know a lot about carburetors. I have asked other mustang people at shows and they don't know anything about this either. First, why is the one line cut, why would they do that (I bought it this way) ? Also, seems to be missing another. I have attached some pictures so maybe someone out there can help me out. Thanks.
