| COPY. HS {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} S/KW. 26th November, 1935. C. Chayne Esq., The Buick Motor Car Co., Flint, Michigan, U.S.A. Dear Mr. Chayne, We are just about to take delivery of our Series 40 Buick, and I wonder whether you could give me a little more information about some of the points raised in the specification - (1) Are you satisfied with the timing chain on this power unit ? Do you think it is as quiet as the gears you previously used ? What do you anticipate its life will be ? (2) On this car you have gone from an up-draught to a down-draught carburetter. Do you find it is as easy to get good slow running with a down-draught manifold as with an up-draught manifold ? (3) At what depression does the Marvel carburetter run at 3,200 r.p.m. full throttle ? (4) Is the streamline(Experimental Streamline Bentley B.23.A.E)d combustion chamber and venturi type intake and exhaust ports a Sales expression, or does it really mean anything ? (5) Do you really get any advantage with regard to the pistons being off-set towards the camshaft 3/64" ? (6) Why do you copper-plate your exhaust valve stems ? Do you think that you will be forced into using stellited valves or inserted valve seats by the increasing quantity of TEL in the fuel ? How is it that you manage to get away without such inserts whereas Chryslers and others are using them? | ||
