john deere 4010 throttle problem

[rca1]

I had a hydraulic leak on my 4010 between the control levers and under the steering wheel counsel and next to the gearbox. I loosened several hydraulic lines, including one small 12 inch long line directly under the steering gearbox. Since doing this, the throttle lever has lost it's resistance and the rpm has significantly decreased. I can increase the rpm's by adjusting the linkage, but it is not running very well. It lacks power and seems to start fouling the plugs. What could be causing this condition?

Thanks,

If you're meaning throttle handle won't stay where you put it then friction pad(parts key #12) may have become oil soaked. You could try tightening bolt(parts key #13)
