Messrs. Rolls-Royce Ltd. Derby. Dear Sirs, I thank you for your letter of the 21st instant and enclose copy of my reply to the letter from Conduit St.{Capt. P. R. Strong} of the 22nd. I should very much like to have had a chat with the Experimental Department at Derby, as I consider the car well worth taking trouble over to get satisfaction. If Kingsbury Depot are prepared to do what I wish in the way of the steering, I have no doubt at all that it can be got satisfactory from my point of view. They can, of course, also deal with the voltage control and the stone guard. Two points, however, which may be rather more difficult are: (1) Detonation which occurs with any fuel between 2000 and 3000 revs. and which is not cured unless the spark is retarded to a point at which an appreciable loss of power occurs. (2) Idling: I do not expect perfectly even firing at slow speeds when idling, but what I complain of is the occasional harsh thump at any idling speeds below 600 revs. The propeller shaft shudder that I referred to, before, is probably inherent with the Hotchkiss drive, and I expect it will have to remain. This last point does not worry me personally very much, but is rather criticized by others. | ||
