The sticky throttle got me too.
I messed with the throttle cable and stuff then someone told me to turn the idle screw a little bit and the sticky throttle was resolved.
The throttle butterfly/plate inside gets wedged or something at the idle postion.
When the throttle was sticky, I would buck off the line sometimes because I had to apply enough pressure on the gas/throttle to pop/unstick the throttle.
When I would press on the gas, it wouldn't go then I give a little more pressure and the throttle unsticks.
It was also intermittent. Would only do it when the temp outside was colde.
Well, I turned my idle screw about 1/4 turn and my throttle hasn't been sticky since.
