Hope the photos might illustrate Malcolm's Lyon's method for required double or additional throttle return spring side draft Zenith. This does rely on having bicycle wheel spokes somewhere in the workshop. In the spoke picture the nipple should be just about visible below the improvised bracket on the chassis rail. Malcolm doesn't charge a royalty for use of his patent method, he expects a pint at Shelsley or Prescott each year, or both.
