| COPY FOR FILES ONLY. 601n 8.2.39. IGNITION COILS. Herewith a report by Brazier on ignition coils, apparently we have equally as good R.R. coils as anything other makers can offer. With regard to the question of fitting a stronger choke springs, this has been tried by Sales and others, and condemned as being too easy to get over rich when starting. It was decided to revert to the present weaker spring. Rm{William Robotham - Chief Engineer}/F.Dodd. | ||
