Harold Whyman - Experimental Manager} Rm.{William Robotham - Chief Engineer}9/ML.29.5.40. RUNNING AFTER SWITCHING OFF. It is noticeable that 9.B.V. and 4.B.50 are much worse for running after switching off than 11.B.V. and 30.G.6. We should be interested to know the engine specification, ignition, setting or any other variation are able to give you any idea to account for the differences.
