Question; What do the rest of the cylinders read?
average good compression should be 150 to 160 lbs.
If #3 is the only cyl. that is low, it's either a burned or bent valve, or a flat lobe on the cam shaft. If #3 "is" the only one low, that rules out head gasket. You can visually inspect the camshaft by pulling the valve cover. Good luck.
