Guys this kid is like 15 yrs old so go easy on him. (lol) I can tell you that you will not find out what is wrong by speculating dude. I know you have many post will all sorts of question. I don't think you have done anything to actually figure out what the problem is.
I don't take a lot of know how to just pull the head. You will be able to tell alot. Post some pics so we can help you futher. Making post and asking questions will only get you so far, then you have to take the the next step and wrench on it or carry it to someone who can. I think I had seen on some other forums where you had asked the same questions. REMEMBER NO ONE on here can fix it via internet, and if they could they would be rich.
