| To C. from Hs. {Lord Ernest Hives - Chair} X4118 Hs {Lord Ernest Hives - Chair} 4/LG29.11.26. C9/C17.11.26. X4117 X4118 The following is our reply to the features mentioned in H5/LH {Mr Haworth} 12.11.26. (2) Throttle control. We have already sent round a standardisation sheet for the improvements to the throttle control. We have recommended that this should be adopted without running 10,000 miles. (4) Water boiling indicator. We have recently sent a sample of the warning light to Sales, and have received their comments. We are awaiting BJ's signature to complete the std. sheet. (5) Burning of platinum points. The improvements in battery ignition to prevent platinum points burning have been fitted to Phantom cars for some time. We cannot say at present on which chassis the modified switch will be fitted. (7) Tappet knocks and general engine noises. If we are going to reduce engine noises, we want them more clearly defined, than being described as 'general engine noises'. As regards tappet knocks, a new design has been standardised which we are sure will reduce this trouble. As regards engine knocks, thickening up of the cyl. extensions reduces this and this modification is now incorporated on all engines. (13) Squeaking of exhaust baffle. This point is receiving attention. (14) Squeaking throttle and weak control mechanism. See reply to No.2. (15) Engine thud. We have nothing to report on this matter. contd :- | ||
