Please note that in report Ha/Rm.{William Robotham - Chief Engineer}6/WJ.24.9.31 the induction pipe depression in every case is ins. of Mercury, this was incorrectly stated as lbs/sq.in. on curves Rm.{William Robotham - Chief Engineer}30 and Rm.{William Robotham - Chief Engineer}34. In Rm.{William Robotham - Chief Engineer}38 the dotted line refers to the single carburetter, The timing in every case is taken with .013 tappet clearance.
