Trot Salt - Carburation}1/MH.{M. Huckerby}7.3.39. B.80 INDUCTION SYSTEM. On the eight cylinder engine intermediate cylinders are over-rich at low speeds. We think this is due to the inside bends of the inlet branches being too sharp. We have discussed with Albert Ridge, the possible ways of altering an existing pipe so that the bends in question have a more gradual sweep. Will you please authorise this experiment to be carried out. Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} | ||
