Thanks again Jon, I spent the weekend working on the carbs and the casings were warped. Not severely, but enough to be a pain to correct. I built a jig out of 3/8" steel and some "C" clamps and it worked quite well. It is a VERY long process like the article says and I'm hoping that they will hold their shape for some time after this. It took about three hours PER CARB so it's best to have another side project to do when your doing this. It also turned out that the center carb's power valve was hanging up so I dressed it out and cleaned it up and now it's working correctly. I'm going to build up a couple of spare carbs to have on hand. They shouldn't warp on the shelf should they? I was thinking about leaving the screws that fasten the two halves of the casings slightly loose and then torquing them down right before I need to use them. What do you think?
Thanks again Jon,
-Tim
