The time has come. My Universal 12 HP 2 cyl dumped all its oil in the sump yesterday. While I hope this is just a drain plug,... because it ran like a swiss watch,,,, I am prepared to replace it. She is old, 4000 hrs and not FWC. What diesel engine fits in the space below the ladder? It should have FWC this time. Where does one find a rebuilt engine? Thanks
