Default Clutch Slipping sound or servo going?

I was just out running my buggy and I found it still at medium rev without me giving it any throttle. Is this a problem with the servo or clutch? Almost sound it like it was going to run away if I didn't hit the breaks.

Buggy is an RC8 with a OS V-Spec with a gallon of Nitro on the Motor.

A clutch problem usually causes stalling. My guess is that the carb is sticking or your servo is going.

With the body off and wheels off the ground, hit the gas a few times and see if the throttle returns to it's neutral position. If it doesn't, well, the servo very well could be toast.

If it does return to center but it the motor doesn't go back to idle, then the carb might be gummed up somewhat and it's sticking open or you may need a stiffer spring on the throttle linkage. Some sort of secondary throttle return spring is a good idea as well.

When you hit the brakes does the motor go back down to normal idle???
If it does then youre carb is not closing all the way when you just let off the throttle and then when you hit the brakes the servo is forcing it closed

If the motor runs normal and then idles up real high like you are on the throttle then you could have a front bearing leaking
When it leaks the motor will suck in air causing it to lean out and rev up
