| To RHC. {R. H. Coverley - Production Engineer} Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 23/KW.26.10.34. Spectre(Codename for Phantom III) Induction System and Slow Running. We have run into serious difficulty with the Spectre(Codename 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 Spectre(Codename 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 Spectre(Codename for Phantom III) cylinder head, in which case the sooner we obtain the necessary information, the better.
