| X.4305. Extract from R3/M1.9.22 X. 3614. CARBURATION. I understand from EP. {G. Eric Platford - Chief Quality Engineer} that Springfield have not yet adopted the exhaust heated throttle. My impression is that this should be adopted on both the English and the American cars as soon as convenient. We understand that the re-evaporative system is adopted on American cars but not on the English cars. It would appear that this feature should be on both production cars. R. {Sir Henry Royce} | ||
