hey all-
so, i bought this baby (the 1982 euro model 250) a couple weeks ago, and am trying to diagnose some stuff. there's some weirdnesses with starting, shifting, and running that i'm guessing (?) may be vacuum related, and i could really use some help. (Note the attached photo of current vacuum routing).

FYI, she's got the 123.921 inline 6 cylinder motor, a 4A1 carb, an automatic transmission, and 261k on the clock (no idea about history).

Issues:

1) When shifting into Drive or Reverse there's a good 4-5 second delay before she'll engage. (transmission fluid level's full and bright red).

2) She will not start when in Park (just clicks). She'll start great in Neutral.

3) She'll do a weird short engine rev in 2nd gear sometimes.

4) Upon accelleration, she'll do a big hesitation/stumble before engine rev.

There are a few missing vac lines, and I have NO IDEA where they are meant to go. Please see photo! (In the green square, there's a 'capped' switch i'm guessing is a thermo time switch(?) that I have no idea of the proper routing. In the blue square, there's a couple lines heading into the firewall which don't have mates.)

If anyone's got advice, or a diagram, or a photo of the routing on their own 250 or similar, I'd sure love to hear!
