BENTLEY PETROL CONSUMPTION. ------------------------- A successful reduction of petrol consumption of 4 to 5 m.p.g. has been obtained on Bentleys by the fitting of the special High Pressure Coil (Delcos). The gaps are opened up to .030", the low speed setting of the carburetter shows up slightly rich and can be cut down a little, otherwise no other alteration is necessary. Normal speeds up to 60 m.p.h. have been obtained. G.{Mr Griffiths - Chief Accountant / Mr Gnapp} W. Hancock. | ||
