Rm {William Robotham - Chief Engineer} /Swdl. {Len H. Swindell} 200a 6.B.IV. Rm {William Robotham - Chief Engineer} 7/R.21.2.38. With reference to Daily Report dated 15/17.2.38., you will notice that using a thermostatic control on the engine instead of thermostatic control radiator shutters has brought up a complaint that the mixture goes weak under cold atmospheric conditions. We should like you to consider some means of ensuring that the air temperature does not fall below a figure sufficient to give reasonable carburation whatever the outside temperature may be. We suggest that an air intake through the rocker cover might have the desired effect, alternative-ly some sort of exhaust scoop. Rm. {William Robotham - Chief Engineer} | ||
