Took it apart this evening: very cruddy. Lots of carbon/coke, and some wetness in there too. ( Oil? ) I'd say the passages were ~50% blocked, or worse.

Anyway, I'll get some pics of the passages, clean it up and put it back together on the weekend probably.

Hopefully that fixes the engine "bucking" problem I experienced under light load at cruise.
