| X4228 Extract from E2/G8.10.21 X.4219. 8.10.21. X.4228 (struck through) X4387 We are proceeding to design a pilot jet for the Goshawk carburetter fitted with an automatic valve somewhat on the principle of the starting carburetter, of which you sent us a model. We are also designing a silencer for this carburetter to bolt on to the main jet and extra air intakes. The remainder of the control gear is in hand for the Goshawk.
