However I would think so as there is no screw and when I put it back together it is only 100mbar now, I'm sure nothing is broken and I did use sealant to make sure cap is sealed when on place, but still not enough pressure, so I presume that screw is something that is between spring and diagraph and shot somewhere I could not find it, must search more.
I believe that it is not too big task to adjust it so that I get correct amount of vacuum, however I'm out of quick glue so need to source that first.
Another thing, gearup side is activated, but only with very low throttle, I doubt that it gets activated very easily when driving, certainly not when accelerating. I don't remember reading that it would had vacuum sensing part, only rpm and those three switches that make kickdown side activated.
I believe that I have missed something?
I did also put some paint to car, even weather was bit cold for that, but rust at lower corner of windshield was something that I had to cover so that changing temps of this spring time would not make it worse, so I sanded it clean and put zink and rost primer to it, still needs proper paint, but it is now covered for now, until weather gets better.
Sadly I managed to damage windshield rubber even I did put tape to protect it, clumsy hands of mine....

Just note that it does indeed still need proper fix, which includes removing windshield, but that is not possible until summer, so it is just to keep it from getting worse as at this time of year it is getting snow, water etc bit too much.
