5. Sam, regarding the orifice openings: I'm sure you're right, though I'm a newbie to MB's and am speaking as a rank amateur, that the orifices are fine tuning methods for delivering precise vacuum to the different components while ensuring that the brake booster always receives sufficient vacuum. That being said, I would not mess with them unless, for instance, I could not get sufficient vacuum at the VCV to reach my starting point of vacuum (formerly 14", then 10", now 12" Hg). I would love for a more physics-minded reader to give an description of how much a particular orifice size restricts vacuum, for instance, how much a .8 mm orifice restricts 22" Hg.

If you turn that clip on the linkage rod, it functions quite nicely.
As for the orifices, have you ever tried to set up a fish tank? If you have too much hose on one side of a splitter, you will get just about all your pressure through one (the shorter) hose. If you would put an orifice on the shorter line, you can force air flow from both. Same idea, but reversed.
