The vertical line ,from the pic, shows where the guide should point. The horizontal is where to trim guide height. The oval is where to widen or grind straight, but dont go into the tall portion of the floor/shor side too much, stay in the oval, and blend it. Point the guide to the middle of the port window.
Trim the guide about 3/8.
You've already removed the guide kink enough, do those things i mention and it will pick up substantially. Have fun!
