Plugs. I have examined a further six sets of KLG. FE. ignition plugs, average mileage 6,000, which do not show any signs of the centre electrode burning, or widening of the gaps. So far there has not been any evidence of failure of these plugs in Service. Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} | ||
