F.10. CARBURETTERS - IMPROVED X. 3933 RR. TYPE FOR VEE. X. 3841 It would seem necessary that the pivot for the float must have centre at the side, thus - Perhaps it would be convenient to make a single float and put a duralumin wire bolt through a central light tube for convenience of getting together. It would seem necessary to cut out idler jet which the level falls in the emulsion jet, as Mr. Lovesey etc. suggest. The action of the Cluadel diffuser emulsion scheme must follow some laws which are practically impossible to foretell, so it is a great question of endless testing, being much less manifest than RR. car carburetters which are comparatively easy to modify by theoretical laws, after finding experimentally their defects in metering. I have been looking out for a rough scheme of the above from E.{Mr Elliott - Chief Engineer}, but owing to influenza (fortunately not serious) I have been out of the running for a few days. | ||
