| E.{Mr Elliott - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} X1692 Hs{Lord Ernest Hives - Chair}5/LG3.7.22. GOSHAWK - CARBURETTER. X4228 X1692 Is it intended that the glass window in the float chamber should be adopted as standard on all carburetters? We cannot see any advantage in it to the customer. Once the level has been set at the works, there is no means of adjusting it, neither should there be any necessity for it ever to be altered. All our experience on the 40/50, we have never had any cause to desire a window in the floatchamber. If the customer ever uses a very heavy fuel, we supply them with a new float to correct the level. In the case of the Marmon in which they have a glass float chamber, there is no mark showing the level, neither is ther any note of it in their Instruction Book. The only allusion they make to the glass float chamber is that it enables the Driver to see that the petrol is actually in the carburetter. We cannot see any advantage gained by the window and we consider it introduces a further complication which may give trouble due to leakage or breakage of the glass, and will increase the cost.
