A friend of mine has a MEP 803a that was used for an off grid recreational planting farm (legal here in Michigan). It has 6800 hours and stopped running one night. I brought it into my shop to take a look and have found a broken connecting rod. But the bigger problem is sludge, and lots of it. Wondering what the group thinks about rebuilding vs just junking the engine. Not sure if I could ever get this sludge cleaned up.
