| 666a Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} from Rm.{William Robotham - Chief Engineer} Rm{William Robotham - Chief Engineer}4/R.4.8.39. Herewith ECD.1376 showing the design scheme for the throttle operation on the 8-cyl. car. You will observe from the Graph that we should have reproduced the Wraith Throttle opening on this car. We believe that some of your trouble may be due to the exceedingly awkward angle of the accelerator pedal. We should be glad if you would check over this, and see whether it is the control or the pedal. Rm.{William Robotham - Chief Engineer} | ||
