I also have the TT Pro .61. It's been great so far. I've had it for a couple of months now and it runs fine and idles very well. At first, I had some trouble getting the low end, idle mix adjusted right. It was set too lean from the factory- for some reason I assumed it would be set on the rich side to begin with. When I richened up the bottom end, it has run perfectly ever since.
