If the problem persists, take the horn back to Custom and have Kevin Powers (their repair technician) work on the valves.  He may have to lap them to loosen the tolerance a bit.  No matter what, I would take it back and have him look at them.  That is why he is there and did buy the horn there.  I had the same frustation with my Willson.  He had to lap them three times to get them working.  I am still working them in some and the second valve stills likes to hang up now and then.
