I may be wrong but I didn't think you could hit a pull from coming too far from the inside. May a draw or duck hook but not a pull. A pull usually comes from coming over the top. And also just because you hit a push doesn't necessarily mean that you didn't come over the top. Coming over the top will cause a slice but sometimes a small slice could be what you think is a push. Just food for thought. A video of your swing would really help.
