I personally don't know about the Tai Chi's specifics and structure, but it could be due to a port (as in the case of the ex1000). Close the port, and it should be fine. Looked at the dn19 and it seems to have ports. Do you put in your dampers?
dam wish I could try the original KFC. Yup. That's what happened. Feeling empty. Does anyone have anything to watch (yes, I'm talking to you bowei)? I have some on the list, but they don't seem appealing atm.
