Dear Maddocks, With reference to your report, it is noticeable that the Speedometer is reading high. As regards the trouble with the Carburetter, I rather anticipate you may have trouble owing to insufficient petrol at very high speeds - you may either have to work with 4 lbs. pressure or else, increase the lift of the needle valve to get sufficient petrol. I am rather surprised to hear that the Water Temperature rises to 100°C. Yours faithfully, | ||
