Made a new main shaft,it was really worn, bushed both that shaft and the choke shaft. Really pleased with the results. Then I screwed up and cracked my bowl body/ dumb move - dang it. It leaks a very small amount/ bairley drips. I am trying to fix it, but now looking for a better one if anyone has one. Its a Carter BB1, using it on my 292 straight 6. It's been working well for several years. I did not see the crack at all. Just noticed seapage, took it off and found the leak. Anybody got a updraft or atleast the bowl part of one? thanks Tom
