| To E. {Mr Elliott - Chief Engineer} from Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} c. to Wor. {Arthur Wormald - General Works Manager} c. to By. {R.W. Bailey - Chief Engineer} +308 Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 9/KW.13.2.35. Spectre(Codename for Phantom III) Carburetters. We are getting better results with the reversed throttle slow running on the 20/25 than we are with the normal carburetter. This applies to petrol consumption. The flooding difficulty with the Spectre(Codename for Phantom III) carburetter is a serious one. The difficulty with the Bentley type of throttle adjustment provided for the Spectre(Codename for Phantom III) is that you cannot set each carburetter individually.
