    Trying to put the servo back on and get the cables connected and set right, I noticed the cables line up from the engine side number '1', to the servo side number '2', and when I set it up like this everything looks right but the valve is working backwards/closing with increasing revs.

    Do the cables swap positions at some point so that the cable runs from 1 to 1, and the other from 2 to 2? - This would have the PV opneing at the right time again, but I do not recall those cables being crossed over before I took it off...

    HELP! I'm almost ready to put it all back together now and am dying to do so before NYE which is also my birthday!

    Thanks! ',;~}

        Cheers buddy, I'd searched and just turned up gibberish that confused me even more, but once I ignored all the threads claiming the pulley rotates clockwise for PV opening, and set the cables back as they were supposed to be (1-2, 2-1) it all made sense again - it must turn anticlockwise viewed from the LHS to open it couldn't work the other way! Anyhow, it's all up and running and I've fully re-dressed her and given her a wipe over and a run up and down the road. All seems well enough but it feels like the PV opened more and earlier before I tore it down and serviced it, I think it had been adjusted from the normal peg-in-hole alignment perhaps, but it's al good enough for now and if I want to tune it a bit differently for preference at least I know what I'm doing now! Time to ride it some more whilst I think about sorting my carb tune properly down the line. 🙂 Cheers Calum!
