Rebuilt my carb tonight - looks pretty good (not that I really could tell the difference!) but when I took it out, I discovered that the choke heat pipe is broken about an inch above where it connects to the manifold. It was covered by the cancer-cloth sheath. I've found the part (pipe) listed as no longer available, but in doing so I also see that it's supposed to connect at the manifold via a flare fitting (I think that's what I see anyway. . .). Right now I don't see any type of fitting there on mine - no way to remove the little stub. What can/should I do here? Can I use a bit of hose and some clamps to rejoin the two pieces at the break?
