It's always nice to know I am not alone. I can't imagine why there would be a slot except for it to be an adjustment slot so having a set screw in there seems very wrong. I hope someone comes in with some answers. I am supposed to be working on 10 other things right now but this 306 is making me crazy and if I don't get answers I will most likely start by taking that set screw out!
