I tried this car on Friday afternoon last but owing to the fog, was unable to get as far as I had otherwise intended. It was rather difficult to form as full an opinion of the engine as I should have liked owing to its not being in very good running order. It was missing very badly on battery ignition and struck me as being less smooth than in the case of the previous one I tried. This may have been due to such local conditions as misfiring, etc. I also had a suspicion that the carburation was not entirely free from irregularities, as the engine frequently stopped when the clutch was out,* although I think that in most cases there was sufficient throttle opening on governor * This might have been due to a stiff or sticky governor. Headlights also failed. However, I take it this test was more for the purpose of criticising sundry points about the car rather than the performance of the engine itself which, so far as I was concerned, was quite satisfactory in the previous car on which I reported. To deal with the various points, the following are points which I did not like:- (1) Instrument Board. This, I consider, is much too low down and the knees of the driver and passenger almost entirely obliterate the instruments from view. Arranged as low as it is in this car, I think it is most undesirable and I would like to see it brought up much higher, where the instruments cannot be obstructed from view and are more easily visible. (2) The top of the brake lever came so near the Instrument Board that I caught my fingers between it and the Instrument Board. (3) I quite agree with Hives that the operating mechanism for the shutters should be more substantial and more visible. These affect so much the temperature and are really an important fitting and one liable to need a considerable of operation, amount - 1 - | ||
