Alright....after 9 years with out ever adjusting the valves (but making 2 rebuilds on engine) I finally think I need to adjust them. I am getting knocking from the valve area and think this is it. Sine my a arm is in 3 pieces I might as weels adjust the valve. What do I do and how harrd is it? I got a book but I dont understand it. I am afraid something will go flying [img]i/expressions/face-icon-small-blush.gif[/img]
