I've got a 2000, Bobcat 773 G-Series machine with 1100 hrs. on it and it has been a really good machine over the years except the throttle is becoming a bit of a pain. I've had other machines that will reduce throttle if I come across an unexpected rock and the machine gets a sudden "jolt", and this machine does the same, but now it's gotten to the point where it will reduce throttle speed just by running on flat ground from area-to-area hauling soil or whatever, to the point where I pretty much have to have my right hand on the throttle arm while I'm operating the machine most of the time. As you might imagine it's quite frustrating! I've checked for some sort of an adjustment at the base of the throttle arm where it pivots, and followed the linkage right back to where it mounts to the engine and everything is tight as a drum and, seemingly, working well. Has anyone experienced this and/or know of something I can adjust/tighten to prevent this "throttle creep?" Any help or suggestions would be greatly appreciated.
