Yanmar YM186D & Ford LGT14D Dixon Z BX2200D Kubota
Now this may not be a good thing I did but , on my old Kubota , I replaced the fuel filter and in stead of filling it with fuel , I filled it with deisel conditioner(STP). Screwed it back on and started tractor. Ran a little rough for a while but once it ran out and started running on diesel again , it was ok. No ill effects. I'm not even sure if it did any good. Tractor runs smooth , although it did before the treatment. Might be worth a try ? /forums/images/graemlins/crazy.gif
