Thanks. > > David Porter R.P.T. > St. Louis, MO Yes Sir. There was a post on this recently. The action brackets are probably growing in size. This is for real!!! I have a Weber in the shop with the same problem. The action brackets are used on Weber, Young Chaing or Sammick, and Wurlitzer...all made by the same company. My job is being paid by Weber as warranty work. Unfortunately, it turns out that the action needed more than just a change in action brackets and let-off / drop adjustment. I've had to adjust lots more. Yes, I compared the new action brackets to the old action brackets...the old ones are indeed taller than the new brackets. Weird beyond belief.
