This helped some. It's better but still not perfect.There are YouTube videos showing how to center the blade, don't go bending your lock bar! Search for "Blade Centering in YT.
There was one specifically on the 566 but I can't find it at the moment because "Blade Centering" isn't in the video title.
K I did a bit of searching and found this one but I'm sure there are others. https://www.youtube.com/watch?v=paRewmjnFl0
