throttle won't open on 300e
 

putting car back together after valve job, now the throttle only opens about a quarterit feels like the throttle plate but nothing came off the intake, unbolted it from the head and the only part of it I removed was the link going under the manifold, also is there a vacuum line going to the fuel reg as there is a short rubber hose but I can't find any spare vacuum lines and in my pictures I can't see anything the cd i have shows one but doesn't say where it goes, thanks for any help as I am starting to need it back on the road
