Very high idle problem

[rupecopp]

I took my bike out today, but unfortunatly I couldn't use it.

It's 2002 ec200

I started the bike in the normal way, with the choke out and second kick it fired. But it went straight up near to the red-line and stayed there when I pushed the choke in it stayed there. It kept doing this and was idling irraticly and mainly screaming the nuts off it.

It acts as if the throttle cable is sticking, but I've checked it about six times, as well as a few helpful other riders. And there is not a problem, it's lifting the slide, and snapping shut.

I also took the carb out and gave it a quick clean with a rag, but I couldn't see any dirt in it, and the clean made no difference.

I also changed the plug, but this made no difference

I'm going to clean the carb with carby cleaner now, but if this doesn't work I'm completly lost as to what the problem could be (as I have checked, and checked the throtle cable).

Any ideas anyone?
