Hey guys, I've never seen one that wouldn't come out by tapping back and foth with a rubber hammer on the center while keeping up pressure on the down tube. It's in fairly deep (bout a 1/2") so you might have to repeat this a hundred times or what ever it takes. You only move it a few thousands with each tap when you first start but eventually it will reach the top and pop out. Patiences is the key.
