My 2188 feeder house plugs very easy. The slip clutch on the auger has been rebulit and the and i tightened the clutch as much as i could with the rotor wrench. I also checked the slip clutch on the feeder, it takes alot of force to make it slip, the friction plates are ok. Anyone have any other ideas. It is very frustrating we can't even keep the combine full or it will plug. I am also running another 2188 and the difference between the 2 is night and day I rarely plug the other one. Thanks in advance
