| (4) While the spring is excellent for traffic and slow running generally, it is thought that the maximum of 95°C shown represents local boiling at some points on the head, and that the engine would boil the water under hot weather conditions if car was kept at full throttle, say, up a long hill. The rest of the running will be continued with the spring removed. The wind did not even have any direct effect on the shutters. G.W. Hancock. I. Waller. | ||
