| X19180. Hs{Lord Ernest Hives - Chair}3/LG. The Robinhood Engineering Wks.Ltd., Putney Vale, London S.W.15. 30th. Jan. 1923. Dear Sirs, For the attention of Mr.K.Lee Guinness. Referring to your letter of the 29th.inst. We cannot say that we are entirely satisfied with the K.L. type of sparking plugs which we have fitted to our 20 H.P. cars. We obtained very good results with them at first, but on some of the recent production engines which are more oily than the first batch of engines, we had trouble with them oiling up. We also suspect that on the road we occasionally, under full power conditions, have trouble with pre-ignition. We should be interested to try the new spark-ing plugs type K-1-A when they arrive, and will let you know the results. Yours faithfully, | ||
