John how do you go about joining the True -draft -club and due they have a web sight .I have a operator's manual from Jensales and the B.F.Avery book.There is one tractor that I see at some of the shows that I go to and I have talked to the owner but in am not ready to start on the general yet. But would like to have the right engine when I am ready.I have been looking at any hercules engines I come across to see if I can find an IXA and I have been told the IXA are hard to find.I have found some IXB's are the IXK any more common then the IXA is . 
  Hope to hear form you when you get back. Steve
