With reference to sleeve engines. As the double pocket engine seems theoretically and to me practically advantageous from a slow running point of view, and as we have always had the opinion that the Knight pattern of sleeve and the Burt-Argyll might be troublesome on this score due to the position of the ignition plug, I shall be glad if this can be investigated with the Daimler chassis when fitted with our own or Polyrhoe carburetter, i.e. some carburetter which we think right.
