Sparking Plugs. We have handed to Rm {William Robotham - Chief Engineer} /JE. one dozen K.L.G. sparking plugs for trial in the exhaust side of Phantom III unit No.6. This plug has a shorter reach and also a higher heat factor than the standard FF.30X. We understand that the existing standard plugs in the exhaust side were giving trouble due to pre-ignition.
