Heh everyone, I can only tell you from my experience that the jb weld will not work. I used it to attach my 2 barrel adapter to the ford adapter, because of broken edges on my 2v adapt. and when I put the H/W carb on started it up, the carb and adapter fell right off and left just the ford adapter bolted to the log. And yes, I let it sit for 2 days hardening before using it. My first and only time using jb weld. Anyone need a little jb weld?
