Hi. Yes you can either put some washers in there or buy the pink spring. Having a read at some of these posts with the flutter then wossh sound. It seems to me they are put on the wrong way around. The above pic of the fg is put on wrong. Replace the trumpet onto the other side and the vented port where the trumpet was. Then install it with the trumpet facing outwards. You will then notice no more flutter and woosh sound following.
