| Messrs. Rolls Royce Ltd. -2- These two series of tests are stated to be most essential to enable them to plot out the jet correction curves and estimate the alterations necessary. 3. Could you also inform us whether, and if to an inconvenient extent, the functioning of the carburettor is interfered with by centrifugal action upon the float chamber level when cornering sharply. Every carburettor, other than those in which the jets and the float chamber contents are concentric, is bound to be affected by centrifugal action when cornering. While the present disposition of float chamber is mechanically convenient, the question is whether it is functionally acceptable to you, or whether the effect of the centrifugal displacement is sufficient to make alternative arrangements preferable. Your considered opinion on this is especially asked for. We are requested to say that as the final design depends upon the above information, it is hoped that you will oblige by supplying the required details, when, if we are still assured of your interest in these tests, the chief Technical Director, Mr. Mennesson, is prepared to come to your works and discuss a final scheme to embody all your special | ||
