John,

I'm rebuilding a spare pair of H6 carbs as well.  I have them disassembled 
and I'm cleaning everything right now (and waiting on parts).  I seem to 
recall that the initial mixture setting should be 12 flats (but I may be 
mistaken, and I'm curious what others have to say).  The 1/4" jet movement 
seems reasonable (based on my limited experience - that's about what mine 
now on the car move); however, I think they should both lower about the same 
distance.  I don't know if 1/16" is unreasonable or not.
