Jan, I think that the word "cam" is an abbreviation of "camber" and in the context of adjusting an aircraft's wing incidence, it is an eccentric adjuster which can be rotated to change the position/setting/angle of a component. In my aircraft I set the engine idle by means of an adjuster in the cockpit at the rear of the quadrant, using a "penny" washer which I filed progressively more around the edge to get a "snail -shell" effect i.e. decreasing radius from the centre hole. I unlock the screw through the middle, rotate the washer to change the idle speed, then lock with the screw again. The two Bing carburettor idle stops aren't employed and are screwed well out of the way, thereby avoiding strain on the throttle linkage.
