tonyfoale,
Thanks for the observations on the Wal Phillips carb I've never seen one but always been fascinated with their simplicity. There was a popular carb based on similar concept used in USA car circle racing I believe.
To you and Olderdan thanks for the correction as to O.E.C. steering. I did use this idea on a trike front end that was built backwards with one wheel in front as it was set up to move the contact patch to outside of triangle, seemed to work well and a huge improvement over the girder front end it replaced.
