I've tried almost every suggestion anyone has ever given me and I have never been disappointed. I wanted to give it a try and I took out all the filler bars. I didn't have a larger pulley to put on but man what a difference that made. Before I could run about 50 feet at about 2.5-3.0 and gradually slow down when the chaffer plugged. Now I was running 2.6 no problem. I could of pushed it harder but I didn't want to. The cobs are still breaking up but now they are like 3" or bigger. The cylinder clearance is right it can't go much higher up. My clearance markers have been moved, is there any easy way to reset them. Thanks Hyper Harvest II and Pete,
