| We would like to loan you sample Karntoil adaptors for you to test under any conditions of over oiling you may devise as we are confident that you will agree with us that an engine fitted with our accessory becomes absolutely immune from the above trouble. Karntoil adaptors are designed to screw into the combustion head and are threaded on the inside to accommodate existing types of plugs. In view of our claims coupled with your undoubted interest in scientific improvements in connection with internal combustion engines we hope to have the pleasure of supplying a few samples for experiments. Yours truly, K.{Mr Kilner} M.{Mr Moon / Mr Moore} Parndell | ||
