| To BY/HM.{Capt. W. Hallam - Head Repairs} from EFC. X34118 EFC6/T9.1.25. X.3551. WATFORD ROL MAGNETO No.68302 - EX CHASSIS GAK.77. J.C. JACKSON. We have now completed the investigation of the performance of this magneto and attached please find my assistant's report, from which it will be seen that we do not find anything wrong with this magneto, and therefore are inclined to the opinion that the phenomenon observed is a question of faulty timing of the magneto in relation to the battery ignition distributor EFC. | ||
