Yes, it was, and then came all the rest of the anti-pollution add-ons, until the computers were able to do more of the work. I didn't recognize the term "draft tube" until I saw the explanation. Back in Nebraska we knew them as "breather tubes." They were usually designed to interfere as much as possible with getting at other parts. -- David Lininger, kb0zke EM37kt Rev. 2:10 kb0...@gmail.com
