[STAMP: Hs{Lord Ernest Hives - Chair} NOV 17 1922 RECEIVED] Ref. Hs{Lord Ernest Hives - Chair}3/LG. 15th November 1922. Messrs Rolls Royce Ltd., Nightingale Road, DERBY. Dear Sirs, With reference to your letter of the 10th instant, the adjustment provided for slow running with engine idling is set by a small hexagon throttle stop screw which decides the permanent opening of the throttle under these conditions. Naturally the air control gives you the variation of mixture to ascertain the correct mixture which with the correct taper needle fitted will give you also the right mixture for high speed. Trusting this is quite clear. Yours faithfully, For F.{Mr Friese} H.{Arthur M. Hanbury - Head Complaints} ARNOTT Ltd. E J Arnott Director. | ||
