| contd :- -2- fitted front brake jaggers cannot occur, the section of the front drums might be stiffened somewhat to reduce distortion and thus increase the period which can ellapse before brake adjustment is necessary. We are awaiting the alterations to increase the rigidity of the rear brake linkage on EAC.7. STEERING. The speeds of the Phantom are such, and the general standard of other car steerings has so improved, that we still have customers that we cannot satisfy with regard to steerings. We believe that we could eliminate these complaints if we had a means of applying a small quantity of spring loaded friction in the steering column. EAC.7. steering is waiting for a design to alter the geometry. We have experimentally tried a shorter pendulum lever which improves the steering. We are trying dropping the front of the spring as well which we anticipate will give still better results. PETROL SUPPLY. We still consider that the Autovac has some most emphatic drawbacks - the worst of which is its effect on the slow running. However it also is noisy and fails to supply the required quantity of fuel when the engine is run under full throttle conditions for any length of time, even with the present large depression in the induction pipe. When we improve the performance of the engine by reducing the induction pipe depression the Autovac will become even less efficient. We have tried and rejected the Auto-pulse. We think that some type of contd :- | ||
