| EFC. X4021 24.11.26. POINTS TO BE DISCUSSED WITH MESSRS. NORTH'S (1) Punctured distributor on one of two magnetos on Falcon X. (2) Access of oil to contact breaker; does it come from spigot end ? (3) Bad sparking in advanced position; is break advanced too early? (4) Cause of only one spark for two breaks, i.e. every other break; is it due to asymmetry of flux paths ? (5) Position re other four magnetos sent back and two further to come. (6) Position re improved contact breakers. EFC. | ||
