If you've tried all the linkage suggestions listed below, there's a good chance a whole bunch of crap built up inside the horn and around the valves and is causing that noise. If you haven't brought it to a professional to give it an acid wash since you got it, you should, even if it isn't the cause of your valve problems. Cleaning that junk out will make a big difference for playing and for mechanics.
