Ah!

I haven't taken the time to understand auto beaming rules yet.  I 
usually just manually beam some of the notes and the rest seem to follow 
along:

\set tupletSpannerDuration = #(ly:make-moment 1 8)
\times 2/3 { a16 b a b[ a b] a b a b[ a b] }

Maybe now would be a good time for me to learn this.

Are you saying there isn't an auto-beaming solution for you?
