| N-W. Hs{Lord Ernest Hives - Chair}/WST. WST 86153 BrE/H.8.1 0.34. re Cars Fitted with Wireless Installations. With reference to the above, we are getting more and more frequently complaints from customers of fouled sparking plugs. There is no evidence of overoiling, but the electrodes appear to bridge almost daily with hard particles of dry carbon, which goes to prove that the sparking plug, when fitted with the suppressor, is not hot enough to keep itself clean. Are you able to help us in any way, as, of course, with the existing conditions we are not able to do anything to cure these complaints ? It would almost appear as if a hotter type of sparking plug should be tried. Perhaps you have had experience in this direction, and we shall appreciate any information which you can give us. Br.{T.
