Never experienced this before If the spark plug is out and when pulling the pull cord the engine is nice and quite turns over perfect. When placing the spark plug in (correct plug) it makes a noise like the blade is hitting the side of the mower (blade and shaft are perfect) It seems when under compression the engine makes noise. I replaced the timing key and the lawnmower starts for a minute or less making that noise and the engine stops and the timing key is broken again. I removed the bottom end of the engine and everything looks perfect the only thing I can feel is that the piston piston rod moves a bit from side to side on the crank-shaft but will not move up and down at the piston rod. Any suggestions
