Thanks guys.....moonshine, should I go ahead and hard surface the edges before I run themIJ The only other change I made was to extend the last helical into the discharge area hoping that would help also: going by the info on the mods page. I run 3 62's in sometimes green stem soybeans, I'll try anything to help get rid of the "constipation" in the cylinder if you know what I mean. Thanks again fellows! Great site
