| Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}2/AD30.11.31. contd -2- Carburetter. We note that the air valve stuck. We think this is important and that you should not clean the air valve daily because cheap carburetters such as the S.U. only require attention every 10,000 miles or so. If our carburetter will not work as well as the S.U. in this respect then we should know the number of times it gives trouble so that we can get the designers to improve it.
