Experimental Dept. cc - Mr. Burton Mr. Bagnall Mr. Ross Mr. Allen cc - Mr. Bailey Mr. Hives FROM: Mr. Olley CARBURETTER - SECTION 5080 Aluminum Alloy Suction Chambers In view of the repeated tendency of these to "gall" and seize when the car warms up and when the air valve is used vigorously by repeated accelerations, let us abandon this experiment at once. D-3688. At the same time let us keep the four valves for trial when we make the acceleration and popping tests on the dynamometer. OY. Maurice Olley | ||
