I'm currently rebuilding my carburetors on a 1972 CB350 and I've encountered an issue while attempting to set the float height. The spring device in the float needle works just fine, however, every time I attempt to set the float height, the float presses on the needle and compresses the device. First, I assume that the float height should be set with the float just resting on top of the needle, not pressing down on it? Second, is it normal for the float to always press down on the needle? The only way in which it does not is if I very, very gently lift the float up and lightly set it on top, although, even this is difficult without pressing on the spring device in the needle even just a bit.
