| -3- The window winders are badly placed, and the windscreen wiper is very noisy indeed. The pedal position is not good, and there has to be too much movement of one's foot when going from the accelerator to the brake-pedals owing to the brake-pedal being so much behind the accelerator pedal. The cut-out is a very great success and the exhaust note is very pleasant and free from boom, and this fitting I am sure will be very popular, and is, in my opinion essential, also with an engine which turns as fast as this one does it is very difficult to detect a misfire at high revs. The present cut-out when open causes an exhaust smell inside the body which might be overcome by deflectors. It might be a good thing to have all the aluminium parts of the engine polished (such as valves, rocker cover etc) as this would make it look less like the 25 H.P. engine, and if it were possible to make the exhaust manifold a little more imposing it would, I believe, please the owner. We hit the lowest brake-rod and as this is rather low I think it should be protected with a guard if it is impossible to move it higher. The petrol gauge only shows gallons. It would be convenient if it also showed litres. The oil temperature on a long run varied between 70º and a little over 80º, a little high for this time of year. The radiator temperature calls for no anxiety and will, I think, be more than sufficient for the most trying conditions. The petrol consumption for the whole journey was at the rate of 14.64 miles per gallon, which is not bad considering the amount of gear work and the speed at which the car was kept running. The steering would be much more pleasant if there was less castor action, as at present on a highly cambered road it is quite an effort to keep the car from running down the camber. Bm. | ||
