Outer Limits 4x4 Board

Hey Guys (and gals)

I have noticed my lil zookk ain't feeling her best atm.. she seems to be iddling hing.. not constanly just randomly.. she normally diles around 800-900 rmp but lately has been as high as 3500. this is random too sometime after going up a steepish hill keeping at the 70k limit others coming down my street on a moderate hill hardly making the 50 limis it the 200 odd meters.
Anyone got ideas on what might be doing this?

when she's iddling high I've truned turing her off and turing back on but no difference.
when I am driving i can feel her go back to normal.. amount of power she;s gettign drops enough I can feel it..
the revs are even staying high after gear change somtimes I find just putting the clutch in & letting it out drops it back to where it should be.

so again.. ideas anyone?

If coolant water is too low, this can give erratic idle (water temp works the auto choke)

Poor fuel or dirty fuel, or in some zooks ethanol and ultra unleaded can be a prob.

there is a few parts of carb that lift the idle when various events occur, need a carby expert to explain that

crud in fuel tanks, filters, carby and lines can move around causing issues.

my moneys on the choke

Yeh my carby did the same thing with the high idling, it would also try to die on me and only a kick in the throttle would get it revving hard again.
I hate carbys and couldnt be bothered fault tracing so i just ripped it out and am currently fabricating a custom manifold with sequential injection.

Sticky linkages?

spray some WD40 around the back of the carb and both ends of accelerator cable... mine does it occasionally
