To be honest, the only parts I like in his solo are those before the G chord turns up. After that it's falling apart at least somewhat for me and more like some "whoops, that chord" affair, there's no continuous thread through it all anymore.
But then, I actually happen to like less Steely Dan guitar solos than most guitarists seem to do - which has likely to do with the parts they come up with to solo over. Take "Kid Charlemagne". I sort of like the composition/arrangement. I also like Carlton and his playing in general. And I like the end solo. But the main solo is something making me not listen to the tune. It's like "inaccessable" or whatever one might say. Just doesn't flow naturally. At least not for me (and I'm defenitely not unfamiliar with more complexed harmony and stuff). Fwiw, I don't even like Jay Graydon's solo on "Peg", which gets a truckload of reputation.
And just before someone gets at me: I can both understand why people like these solos and I can as well appreciate their value in a music-historical context. After all, these were bringing jazz and fusion vibes to pop music, which was quite an achievement (see La Szum's and your posts about SD's achievments in general - which I totally agree with). It's just not for me.
