So looking at it again with the problems I am having. The tightening of #9 screw causing the LCV to not move is definitely a "shim" issue as dwcraig pointed out. I tried the foil thing and it didn't work. Very difficult to deal in that small of a space. I will probably look for some washers that will fit in there. But when you tighten the #9 screw it should clamp down #3 and #8. But what it is doing is putting too much pressure on #5.
I will post if I can find a good solution.
The UC (entire part A) will be "loose" or have a "shim" unit it is connected to the BODY (entire part B). This is normal and happens on the authentic version as well.
You must have part 9 secure and have part 8 in the right position (the bottom is squared) in order for the entire device to work right.
I normally assemble all of the UC, then get the Body ready, place the spring that connects the two and screw it down all the way so the juice control is wide open.
Like I said, the "shim" is normal until the UC and BODY are assembled. If it still shims you are either doing something wrong, missing a piece or have a bad clone.
