| R.R. 238 a (400 T) (S.C. 536 15-2-16) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 1546. To Na.{Mr Nadin} from E.{Mr Elliott - Chief Engineer} c. to EH. 17/7/16 COPY. E3/W15716. July 15th, 1916. RE BUGATTI CAR. With reference to the above Mr Royce wishes to try a Claudel Hobson carburetter so as to obtain a comparison with the existing Zenith system. Would you kindly communicate with Messrs Claudel Hobson and ask them what size of carburetter they recommend for an engine of 75 m/m bore and 105 m/m stroke. Mr Royce is of the opinion that the 30 m/m Zenith at present fitted to this engine with 16 m/m choke tube is too large to get good results all the way down the scale and thinks that a possibly suitable size for the Claudel Hobson would be 20 m/m.{Mr Moon / Mr Moore} The carburetter selected should have a flanged joint. Mr Hives has been dealing with the matter of rigging up a Claudel Hobson carburetter on the Bugatti and perhaps he would say if he has been able to arrange anything. Mr Royce thinks if we actually had a carburetter down here we should possibly be able to see more quickly what is required. E.{Mr Elliott - Chief Engineer} 2246 | ||
