We have had a number of complaints of corrosion of the copper float in the carburetter. BY.{R.W. Bailey - Chief Engineer} instructed some standard floats to be nickel-plated in order to overcome this fault. We have run these floats for some time on a car and find that they are undoubtedly an improvement as regards resistance to corrosion. We recommend that we immediately nickel-plate all floats. In future we think it would be better to use brass spinnings for the float instead of copper. Brass is universally used for this purpose and is what we have always used on the Goshawk and Aero engines. Hs{Lord Ernest Hives - Chair}, | ||
