Brian,

How do you "open the rack"? It that by moving the throttle linkage from idle position to WOT?

Oh, BTW, thanks again for your help. I ordered the orifice #63 from the diagram. It will be in this week. MB showed it to be 2mm inner diameter for the Federal emissions group. Also, MB does not list the part as an orifice any more. They now call it a nozzle. FYI, thier vacuum diagram was a bit different than the diagram posted here, and they had to find an older parts guy who knew about the vacuum systems on out older MB's

I will post a part number when I get it.
