| Y To By.{R.W. Bailey - Chief Engineer} from Rm{William Robotham - Chief Engineer}/GR.{George Ratcliffe} c. HX. c. LA.{L. A. Archer} Rm{William Robotham - Chief Engineer}/GR.{George Ratcliffe}6/HH.9.6.38. WRAITH CARBURETTERS. With reference to the fuel level on the above carburetters. We wish to point out that with the .750" level agreed upon, there is a definite flat spot in carburation between 6 and 10 M.P.H. This is only apparent when after idling at 6 M.P.H. top gear the accelerator pedal is suddenly depressed not more than 1/2" travel. We agree that these conditions may be seldom met with in customers' hands but wish to record it as a possible complaint. Rm{William Robotham - Chief Engineer}/GR.{George Ratcliffe} | ||
