Ricco Kuhn maintenance

I took my horn to Wally's Music today, in Oregon City, OR, to see if they could determine why all the notes on the 1st valve, F-side, don't center. He examined it and said that there are no leaks, he blew compressed air through it, snaked it out, checked for solder in weird places. The only problem he could find is that there is a 1/16th inch gap between the crook and the inner tubing. Also, apparently my valves were never aligned/bumpers trimmed when I bought the horn, so I left it with him overnight. Let's see how much better it plays tomorrow.
