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. | ||
