Is there a trick to this thing. I went to take it out a few days ago..removed the allen screw and then let the quad warm up for about 5-10 minutes. I had a buddy try to pull it out with a pair of pliers and no luck. I rode the quad around and try gassing it..still didnt come out. I then rode for about 2 hours and it still is in there, I was expecting it to shoot out. Is there something I'm missing here?
