another way to centre the point blades is to push a matchstick between the moving rail and the side rail on both sides. that way it is possible to adjust the blades so they are exactly centred and locked in. Another way to got more throw, admittedly ugly but very effective is to elongate the hole in the tie bar so that the motor bar has more room to throw. i have used this on seep motors when they have not had sufficient side to side movemen to switch contacts on code 75 finer scale points.
