Lodge Sparking Plugs. Na {Mr Nadin} (C.for Mcr.) EP {G. Eric Platford - Chief Quality Engineer} 9/W14115. With reference to yours JR {Mr James Royce} 1/J91214, we have tested these plugs on our Demonstration Car and also on the Dynamometer. As regards running on the dynamometer, i.e. full power, high speed conditions, they are reported as being quite satisfactory, except that there is a tendency for a leakage through the joint of the centre stem, through the porcelain. As regards the running on the road, however, they are reported as not being satisfactory, as they give trouble with this firing, especially at low speeds. Also, they do not stand oil, and they are also rather difficult to clean. We have credited the 12 plugs into the stores, to be dealt with as per your instructions. EP. {G. Eric Platford - Chief Quality Engineer} This sheet must be filed with the correspondence to which it refers. | ||
