I have a go kart with a predator 212 on it. Starts up great. I have disconnected the throttle cable. It seems to idle high even though I have unscrewed the idle screw the whole way. I can push the throttle as far back as it goes and it won’t idle down any further. It is creating so many RPMs at idle that it engages the centrifugal clutch and spins the drive wheel pretty fast - to the point where the kart would drive away on its own if I didn’t start it on jacks. When i hit the kill switch and the engine starts to wind down, the clutch disengages and allows the wheel to spin freely. Is there any other way to lower the RPMs at idle? Seems like I should be able to adjust the idle down to the point of stalling but I can’t get anywhere near that.

The governor arm may be too tight, not letting it return to idle. The governor arm is right below the turtle to rabbit sticker, where it attaches to the engine, there should be a little screw. Try loosening that.

Did you loosen the throttle plate...
I ended up fixing the problem by removing about a half inch of spring from the clutch, which now keeps it disengaged until the RPMs rev up a bit. I am going to find the governor screw you mention, however, because I thought that arm was a solid bar vs anything adjustable. It may or may not lower the RPMs any further because the throttle arm is pushed so far back that it bumps up to another part of the engine - in other words even if I removed the governor arm I doubt it widen the low end range. Worth a try though! I really appreciate the idea.
