| URGENT. X4226 To Hs.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} c. to CJH BY.{R.W. Bailey - Chief Engineer} E1/M30.12.21. RE VALVE TIMING ON GOSHAWK II. X.4229. X.4226 With reference to he above, it is necessary to decide what alterations are required to the cam forms and timing diagram. It would be very useful to know what actual timing is obtained on the experimental Goshawk engine, and what clearances hot and cold you are using, and also what were the best results obtained on Goshawk 1.
