If it is assumed that EAC.11 chassis will take the place of EAC.1V. as regards urgency, and also that the EAC.11. will at first be produced with present standard 40/50 Starter arrangement, the following is a list of the troubles which, in our opinion, exist of EAC.11. chassis we have so far tested, and which should be corrected before any cars of this type are delivered to customers :- 1. Retard vibrations. 2. Engine power to be improved. 3. Engine speed to be increased by preventing the valves leaving their seats so early. 4. Steering to be improved. 5. Clutch to be improved. 6. Governed ignition to be fitted. 7. Suction and exhaust noises to be reduced. 8. Brake operation to be improved. 9. Carburation to be improved. 10. Starting handle to be improved. In most cases, modifications have been instructed and experiments are in hand to overcome these troubles but so far, there is no satisfactory solution of them. The following is a list of parts which are necessary contd:- | ||
