First off, I can't find the original thread where I found this picture, but I think it might've been posted by rodster? If so, hope you don't mind me using your picture.
In this picture, I know the insulated tube from the top of the exhaust manifold to the carburetor operates the choke stove. However, how did it originally attach to the manifold? Did it screw in place? If not, then I'm afraid I might have something broken off on my original RH manifold.
Secondly, what does the smaller steel line running from the bottom of the manifold up to the carburetor do, and did all cars use it? And is the smaller line clipped to the larger line with something like a transmission cooler line clip? That's what it looks like. Is this smaller line currently reproduced?
