So Jon, I managed to true up a (spare) Roch B carb via both of your Casting Fixes (dewarp) tech tips -- thanks.
However, one thing that stands out may be the omission of whether the choke and throttle plates should be removed prior to putting the works into the BBQ at 400+ deg.
After finishing the process and trying to reassemble the choke plate and shaft I found that the through-openings were slightly warped and thus binding the brass shaft -- they no longer lined up.
I'm still trying to resolve that issue (without reboring) and to make the choke more moveable.
So, on the second (operating) Roch B carb, should I just leave the plate and shaft in-place and heat it all together?
