This past Sunday I had row # 19 keep plugging, I usually take a pocket screwdriver and poke down into the cup and it un-plugs it, but it would not work. I took the 2- 10 MM bolts out of the bottom of the cup and turned it over and found a 5/16" nut down in the venturi, pryed it out with the screwdriver and all has been good ever since. Hope this helps!
