Auto choke set backwards?

[Gambit]

the CO% is not set correctly. needs set to 2% at idle with the engine breather on the airbox disconnected

that link details setting the CO%

Yes I did check that, but first just to settle my curiousity I sliconed up around the idle screw (it was previously siliconed) and now it is running fine idles perfect, I must have disturbed the silicon that was previously on there, put on I guess as you mentioned about the rubber ring had probably worn.

Thanks again.
