another idle/ISV question

so i have a newly transplanted 3.6 in my 71. it was running and checked out ok when i bought the motor 2 years ago so i wasn't expecting this much trouble from it. what i read about 964 motors (ISV, DME, etc) even perfectly running motors can be finicky so trouble shooting i go...

here's what's happening:
1) car fires up after a few cranks (shouldn't it fire right up on first crank?)
2) runs for a couple seconds then quits

i cleaned out the ISV and noticed there is a sleeve or something inside that doesn't seem to slide. is it supposed to or is this stuck?

there's also what looks like a vacuum port not connected to anything and i feel a lot of air being pushed thru when it stalls.

any ideas?
