I just hate it when it sounds like it wants to die....I checked all yesterday, put another screw with fine oring, set it here and there, the same was happening, when I got to my GF's place closed it again totally and set it with manual, saw my dump valve stays open

gave it some oil and it seemed fine.
Came back this morning, car was idling very low, 0.8.....hated it...checked then saw I somehow managed not to lock the manual screw with the nut that sets the manual idle on the butterfly, it fell out but luckely onto one of the pipes where i found it, put it back, set idling again, seems fine, didn't jump to 1.5 this morning. Dump valve was still open so turned the bolt in more to make it harder to push out, it doesn't shhhhh so nicly now but it stays closed, will have to take it out and oil it properly.
