Hi, I have a kubota bx2230 that I've owned for a few months now and has 972 hours on it. About a month ago the engine would bog down like it wasn't getting fuel to it, so I replaced both fuel filters and it ran great for awhile. The tractor set on my trailer for about two weeks. It got rained on once and when I went to operate it after about 20 min it started to bog down again worse than last time tho. This time it almost died a few times when trying to scoop withthe front loader. Is there a chance I got water in the system? Or might I have another problem. I wa gonna try some fuel treatment and see I that does anything. Tips would be awsome thanks guys.
