| -2- Engine. As delivered the engine was hunting when idling and was idling very close to the mounting period, causing the whole car to shake. This was improved by Rm {William Robotham - Chief Engineer} /GB. who altered the mixture and throttle stop. Still the whole car shook when idling. Also Rm {William Robotham - Chief Engineer} /GB. suggests an examination of the mechanical automatic ignition advance, the pick up being poor on opening the throttle and the engine "pinks" on hills. Exhaust System. This I thought was poor. There is a bad boom at 35 M.P.H. in second under power. (Gear ratios, 1 to 1, .61 to 1 and .291 to 1). Gearbox. I feel that the car would be better off with four speeds. It appears to be a 4 speed box with 2nd. speed missing. Second speed is rather noisy and 1st. speed very bad. Clutch. The clutch is rather difficult to engage sweatly and Rm {William Robotham - Chief Engineer} /GB. says it needs adjustment. Brakes. I thought the brakes, for what they are, to be quite good. Quick application produced thumps and Rm {William Robotham - Chief Engineer} /GB. says these cannot be wholely avoided but brake adjustment would improve matters. Some means of avoiding a too rapid application of the shoes to the drum is called for. Axles. Noisy always and very bad at around 55 m.p.h. Rm {William Robotham - Chief Engineer} /GB. suggests examination of rubbers. Apparently all Vauxhall 10's have this defect to a degree. Noise. (a) The wind noises are above average. (b) The tyre tread scream is not bad, in fact this Cont'd. {John DeLooze - Company Secretary} | ||
