i have the tank and air cleaner off and am sitting there looking at the secondary butterflies and can't help myself any longer, so i take my finger and push them open to peek at whats down in there. i thought they were spring loaded and would "snap" back. well they just stayed open so i pushed the other side and put them back closed. did i screw anything up doing this? do they have to be recalibrated if you move them around?
