| 4473 X.4075. Extract from R6/M19.1.23. RE IGNITION. X.3485. For the sake of reliability, etc. I had imagined that the 2 sets of H.T. wiring should be in separate tubes, the magneto being below the plugs, and the battery ignition above the plugs as at present. Mr. Elliott will at an early date set out the head with the two sizes of plugs. | ||
