Sounds to me that the feeding is the problem. If a 800 head with Crary air reel is out of the question than you should try the suction tube behind cutterbar trick. Do you have corn strippers in either front or rear feedIJ Are feed chain tention springs tightened to 5.1" or slightly tighterIJ Do you have a rock sump kit installedIJ Does one side of header feed better than the otherIJ Have you changed fuel filtersIJ How many reverse barsIJ What position are feeder drum stops inIJ Do you have a chopper or discharge beaterIJ Sorry about all the questions but I'm sure we can get you going with a little more info.
