| To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}23/KW.26.10.34. SpectreCodename for Phantom III Induction System and Slow Running. We have run into serious difficulty with the SpectreCodename for Phantom III slow running due to the short distance between the cylinders and the carburetter. CTS.{C. Trot Salt - Carburation} is carrying out some investigation work, using a Bentley to reproduce SpectreCodename for Phantom III conditions. We should be glad if you would give any pipes he requires priority, as we may have to ask for a complete re-design of the SpectreCodename for Phantom III cylinder head, in which case the sooner we obtain the necessary information, the better.
