(9) SPARKING PLUGS. X.1812. X.1918. It is now reported that the best plugs for the Goshawk are the K.L.G. detachable mica plugs. I would like Mr. Hives to make sure in the event of us using mica plugs that these are satisfactory under all conditions of running, as we found that Lodge detachable mica plugs on the Buick at West WitteringHenry Royce's home town very soon sooted up in use. | ||
