    basically the vacuum thing fights the spring in the hockey puck. Don't remember the specifics but basically the vacuum thing tries to pull the high idle cam out of contact, but the spring in the hockey puck tries to keep it there when cold. If the vac doesn't work it won't ever pull the high idle cam out of contact.

    It probably works just as it should, it just seemed that the vacuum pull-off was already bottomed out but it wouldn't pull it off the cam all the way.
    The pull-off shaft won't go in so far as to click it off the lowest step.

    It just rests on the little nub that the arrow points at. It had a little bit of pressure on the nub for a while, but when the spring starts warming up the nub eventually moves away from the pull-ff shaft.

    sounds right, just tweak the hockey puck if you need it to stay on high idle longer. Since you don't drive it in the winter its really not a major concern.
