Y3949 CARBURETTER CONTROL. X4239 Y4219 Amongst the criticisms made on the Goshawk car, is one relating to the carburetter mixture control and there appears to be a general desire for this control to be fixed on the top of the steering column similar to the 40/50 H.P. The starter jet and the switch could remain on the instrument board - the Klaxon Horn Button should also remain on the steering wheel. I think there is a lot to be said in favour of this suggestion as it certainly is a great advantage for the carburetter control to be made use of by the driver in order to obtain efficient running and is a point which is appreciated by the drivers of our 40/50 hp. cars. Could you please raise this point, if you thought wise, in your discussions with R.{Sir Henry Royce} X4354 Sales were also asking why the automatic control for the ignition could not be complete so that the ignition is satisfactory at all speeds of the engine from starting up to 3000 revs. I have discussed this with FN. which he quite appreciates and feel the job is worth while tackling as being a very important selling point. The impression is, that some hand-control is required but it is chiefly to deal with varying conditions of engine running caused by various types of fuel or atmospheric condition., but once having found the best hand-setting, the hand control need never then be touched, even for starting up or starting on the switch. EFC. has got this matter in hand. contd:- | ||
