| To HS.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} -2- R12/G23/8/20 Contd. The same thing occurred on 6 EX. but it was found that the priming cock was not absolutely over to the running position. It is possible with other cars the passage for the air is not sufficient-ly free, owing to some defect in the piping or cocks. The result WPH's car is that it is quite tiring to pump up the pressure in the tank, if the tank is low in petrol. R.{Sir Henry Royce} | ||
