| EXTRACT FROM THE "MOTOR TRADER". Dated November 22/21. KARSWONE ADAPTORS. W. J.{Mr Johnson W.M.} ROUCH & PARTNERS LTD., of 22, Shaftesbury Avenue, W.1. have sent us a set of adapters shown on Fig. 3, and we have tried them with excellent results, the plug remaining clean even when the engine was intentionally over oiled. The baffle prevents oil reaching the firing points, yet does not adversely affect the power of the engine; if anything the engine runs better and the freedom from plug troubles is worth far more than the retail price of 4/- a set.
