SPARK PLUGS ------------- With reference to Rm{William Robotham - Chief Engineer}/RC.{R. Childs}1/SW.22.8.40, we should like to know from Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} whether the test bed results confirm that KLG. FE. 30 X plugs were responsible for the running after switching off. We are prepared to run Lodge 741 plugs in 9.B.V.
