| -2- Rm{William Robotham - Chief Engineer}/GR.{George Ratcliffe}10/WH.16.11.37. we would therefore appreciate the inclusion in the special carburetters of the smaller .101 needle seating. Finally it may be possible to use .061 main jet instead of the present .063 on these carburetters, if the main feed hole is increased. Yours faithfully, for ROLLS-ROYCE LTD. | ||
