unstable idlling-stalling im going nuts

[GRH]

i had a go with it just now.. but i wasnt fully test it properly as the ****ing bottom screw snapped a piece and i couldnt open it, the gap next to the screw is too narrow to use a socket.. anyways
before tampering with it i tested it using the continuity method as described in the manual you linked, i noticed that it is ok usually but if i pull the throttle wire up and suddenly drop it sometimes continuity wasn't there, pull again drop again and works..
i was able to move it clockwise with a bit of force and continuity is stable. idling seems better now but need to observe and report long term result.
i also noticed if i tap on the sensor while continuity is on, it interrupts it. maybe sensor is dodgy.. maybe forcing it i buggered it who knows.

thank you for the great advice and follow up

A "thin wall" quarter inch drive 8mm socket will fit, whereas a regular half inch drive 8mm socket will not.
