| To Hs. {Lord Ernest Hives - Chair} from Hs {Lord Ernest Hives - Chair} /G.H.Whyman. a. {Mr Adams} to Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} Hs {Lord Ernest Hives - Chair} /Md. 84425. 28.5.32. REPORT ON SPARKING PLUG TESTS. Our next test was to remove the earth point from magneto No. 126900, thus cutting out the safety spark gap, and over a run of 65 miles, no misfires of any description occurred. This proves that our misfiring trouble is definitely due to magnetos, and Mr. West has been informed accordingly. Hs {Lord Ernest Hives - Chair} /G.H.Whyman. | ||
