As a side note, have (had) a Kaywoodie with the same issue. Bought if off Ebay with the issue known for cheap. Smoked it off center for a while, and then decided I would attempt to adjust it back. Took some channel-lock pliers and grabbed it at the base of the the threaded stinger, being careful not to catch threads. A couple of low torque, but with some force, twists and it is good as new. Course, I could have just as easily broken it. Not a bad try-and-fix on a cheaply bought pipe. Wouldn't try it on something that had some real financial or sentimental value.
