X.4228 - 20 HP CHASSIS - CARBURETTER - SEC:5080. With reference to recent complaints of the inconsistent action of the H.S. Air Valve, which result from the small distortions of the Suction Chamber E.51143, caused when screwing up parts which have the threads slightly eccentric or out of square with the joint face, Mr Bailey has given consideration to the matter, and would like you to try out experimental sets which have a definite slack thread, as shown on the attached prints E.53021.
