THE ZENITH CARBURETTER CO., LIMITED. Sheet No. 2. Messrs. Rolls-Royce, Ltd. 1st July 1931. You will notice that in order to increase the efficiency of the hot spot under the carburetter, a baffle has been fitted approximately half-way across the exhaust jacket. We would also advise you to provide the end of the small pipe taking the exhaust gases from the main exhaust to the hot spot with a scoop in order to increase the gas circulation. We would like to know if you intend proceeding with such a scheme, and are of course, at your entire disposal for supplying you with the necessary carburetter. Always at your service, We remain, Yours faithfully, THE ZENITH CARBURETTER CO. LTD. [Signature] LP{Mr Lappin}/IH Encls. | ||
