| THE ZENITH CARBURETTER CO. Sheet No......2............ Limited. Messrs. Rolls-Royce Ltd, Derby. 15.5.40. ..of the carburetter, with alternative sizes of throttle barrel, so that with the same main components, a 30, 36 or 42 mm. twin downdraught carburetter can be built up. Therefore, if you wish to use a twin downdraught carburetter on a smaller engine, we suggest that you employ one of the AA.{D. Abbot-Anderson}25 Models now on the way, and that we make a 30 mm. throttle body for it. In order to make a pattern and machine one sample we shall require 6 to 8 weeks at the present time. We are afraid there has been practically no demand for such a small twin carburetter to suit a 14 hp. engine, hence our reason for not making or stocking this small size. However, if you will let us have more details of the engine, it is possible that a 30 mm. will be suitable by using a small size of choke tube. In any case, we will do our very best to meet your requirements in every way, and remain, Yours faithfully, THE ZENITH CARBURETTER CO.LTD. General Manager. TLT/GD. | ||
