| Actually, isn't he talking about the last section of the Third movement? (Tu-tu toodle la, tu tu toodle la.)
Try two things: If you wish to single tongue it, you would best go to your Arban's and hit 148, all twelve of them, at about 112 to the quarter. If 112 is too fast, well there's your problem. Work that page and others like it until you can do it at 112 up and down.
If you wish to get a cleaner double tongue in this particular context, go to Arban's characteristic study number 5 and do it with the double tongue at about 120 as a goal. Start slower and go faster until you hit 120.
Hope that helps but iffen it does, it ain't gonna be overnight.
