I just purchased a MTH Railking GP 7 and I noticed that the front coupler arm does not protrude out of the engine parallel with the track. The arm is drooping down in the front and only catches the roiling stock coupling about half way in the knuckle, is there a way to adjust how level the arm is to the table. I also noticed that this arm does not want to spring back to center when pushed to either side of its travel. If anyone has an exploded view drawing of the front truck and arm assembly it would be a great help, I can not see very well how this works.
