Re: Carb rebuild II

I have used JB Weld before, but never in the manner suggested. I don't think I am that desperate yet (and don't have a spare carb body around), but an interesting technique.
I don't think there is any damage to the threads on either the carb body or the jet plugs. Both appear to be pretty crisp. (But, maybe the seepage means the diameter of the hole has increased over time). It almost seems to me that a gasket from some other material (or a fatter one) would solve the issue. I don't see any deformation of the bowl where is contacts the gasket/screw, no obvious scratches or gouges. But something is certainly up. I think the area gets too hot to use a rubber O-ring.
I would be a little afraid the permatex would get into the float bowl and then potentially clog something, but I may give the screws a single turn of teflon tape. I think this might work as long as the screws still screw in completely.
I do recall when I first bought the car (which had been in a private museum and seen little use for about a decade) that I would note some accumulation of gas on the manifold, which went away after a short while. I hadn't seen the issue for months. I am now wondering if they rebuilt the carb prior to auction and experienced the same problem. Also wondering if it will improve over time.
