Guide looks fine to me, just like the one I have at home. I would suggest changing your flipper rubber, aligning the flipper to the alignment holes and just play the game.

Unfortunately, those folks that use a straight edge instead of the flipper alignment holes are changing the shots on the game. This type of alignment can really make a game play differently. Hey, I don't like flipper hop either, though I think dealing with it from the lane guide side/flipper rubber is how it should be addressed.
