Hello out there, I recently returned from an 18 month deployment to Iraq, my tractor has sat for this time period with no attention. It started right away but the throttle seems to be stuck wide open inside the fuel injector pump, does anyone have anyidea what I could do to fix this problem

If it worked B4 U left play with it some and it might,hopefully, loosen up with out a overhaul. ....

Welcome home, and thanks for your service.

Start by oiling and moving all joints in the throttle linkage. Next, there's a friction disk (to hold the hand throttle where you set it, against the pull-back spring) which may be too tight, or the spring may have weakened. ....
