    Bad knocking

    I had a missfire in the #2 cycl. found out it was a striped spark plug, so I pulled the head and heli coild it. Igot it all put together, but when I started it up there was a nasty metal click&knocking noise. could it be from over torq. the rockers,or from driving for a month with a dead cycl?
