| matrix used to get plastered up, just like this but we never measured much drop in efficiency & so came to the conclusion that bees had a high conductivity. Now that you are nearing 15,000 miles I am particularly anxious that you should not hear the car, we want at all costs to keep it running until we have the next one ready to come out. Re carbs being affected by temp. The Stromberg man who is here at present says that vapouresation of the petrol is causing the trouble you can tell by removing the float chamber lid{A. J. Lidsey} when a stream of bubbles will be seen rising if some part of the feed or the carbs are too hot. If you insulate the carbs from the head with a thickish packing insulating washer (300) does it do any good, we cannot measure that it does | ||
