| - 2 - lack that the failure is due to leak of oil when starting up and running the engine too slow. The oil pressure is not sufficient to reach the gudgeon pins until the damage is done. The engine requires to be run fairly fast as soon as it is started up. We shall, therefore, carry out this principle when we receive the car again. Tyres. 21 G 1V. We have now run 2,947 miles with the "90" type tyres. The opinion of all the drivers is that - steering no difference, either in lightness or selectivity. Two drivers were of the opinion that skidding was more pronounced, Myself and the others did not perceive any difference. In my opinion riding is harder with the same tyre pressures - i.e.- 30 lbs. rear and 35 lbs. front. G.W.H. | ||
