First you got to do whatever you can to get feed uniform. If on side or the other is not feeding you need to level header to ground (you can cheat with this by adjusting air pressure) this will get you by until you can make proper adjustments. If is having problem all the way accross header in the short beans you will need to look into 3" tube trick mentioned hear or in hyper mod section. Also running head as low as possible to flaten out flex area will help. You may need to adjust ground pressure springs to make cutter bar as light as possible to prevent pushing. Now if it is unthresher pods you need tighter concave clearance and or filler bars. Don't overlook worn out cylinder bars, concave, or zeroing out concave to cylinder as good as possible. If you have tailings return kit to rethresh pods you could shut down sieve a bit. Now after you get more familiar with machine you may want to check out what you have for helicals. You could still have original 3_8" flat iron helicals that have leading edge worn bad, maybe shimmed helicals with 1_4" flat iron, maybe green stem kit which adds a few original helicals on thresher side and hooks up steeper pitch thresher helicals with shallower pitch seperator helicals at three locations, double stacked helicals all the way threw or just thresher side, or some setup of channel iron helicals. Biggest thing these older machines require is cylinder bars and concave in good condition and helicals that will move the type and condition of crop being harvested. Good luck
