I just bought a U, I was told it was running then parked then the owner passed away. I was doing some maintenance on it prior to trying to start it. I pulled the plugs and discovered there were two different plug sizes. 2 cylinders have a Chanmpion D9 (18mm width), and the other 2 cylinders had the champion J6 (14mm width).
The heads have different #'s on them, one has 6E3OT(D9 plug), the other has 10A4207(J6 plug). Which head is the correct one? which plug is the correct one? or can I run the tractor with 2 different plugs? Obviously the tractor has been worked on before. Any help would ber gfreatly appreciated.
