| 1044 To By.{R.W. Bailey - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation}5/JH.25.2.39. 8 Cylinder Engine. Further to Rm{William Robotham - Chief Engineer}/Swdl{Len H. Swindell}'s. report reference Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} 1/MH.{M. Huckerby}23.2.39. With the existing induction pipe, the depression in the riser is the same as the main bore of the pipe, which means that there is some restriction in the induction pipe itself. We therefore require a new induction pipe with a main bore of 1.750. The risers should be the same size as the bigger Stromberg carburetter, so that we can repeat tests with both types of carburetter. In this way, we may be able to make use of the larger carburetter.
