IT RUNS!!!!!!!!!! Cleaned the entire fuel system over last week or so and on a temporary fuel tank got the system bled of air and she fired right up and purrs like a big kitten. i have discovered that my check valve in the small fitting on top of the injection pump is bad as if that fitting is on and the injection return line is on it the tractor will run for 10 seconds or so them die after several ideas i discovered if that small check valve is removed the tractor runs like it should but fuel is pumped out of the top is this normal? im not a professional injection pump man so im asking for any help? Now im going to install my new waterpump kit and see if that will solve the problem of water in the oil, if not im thinking head or head gasket? i hope nothing major as this tractor runs soooooo well. I went to move the tractor and the clutch is stuck any ideas as to how to get the big girl loose? thanks for the help so far and here is a picture of the rear fender placement..
