Dear Sirs,
We have had an opportunity of discussing with our Central Laboratory the best means of fitting our downdraft carburetters on your 20/25 H.P. Engines.
From this discussion it appears that our Central Laboratory is convinced that a single carburetter fitted in the middle of a straight induction pipe should give you all the power required, and at the same time, ensure good distribution at all speeds.
We have therefore prepared a proposed lay-out of induction pipe which we are sending to you enclosed herewith. This lay-out has been submitted to, and approved by, our Central Laboratory, and is designed to be used in conjunction with our 42 V.I. carburetter, of which please find also an outside view enclosed herewith.
-contd.-
