To R.{Sir Henry Royce} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} C. Eg. Wor.{Arthur Wormald - General Works Manager} C. Ds. S. Ev.{Ivan Evernden - coachwork} BALANCED TWIN CARBURETTERS. We send you herewith curve Rm.{William Robotham - Chief Engineer}P30 showing the difference in power output of the twin carburettors balanced and unbalanced. The balancing hole was cut in an extension piece immediately over the top face of the carburetter. We anticipate that the difference between the two curves might be increased by about 10% with the 114° long duration camshaft. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
