I have a cub cadet zero turn mower with a kholer kt735 spec 3013 motor which, I've just changed the head gasket on. the cylinder now has 150 lbs of compression. the other cylinder has 125lbs of compression. I've set the valve clearance at 5 thousands at top dead center. the 125lb cylinder plug is carbon edge up after running, the 150lb side is not firing at all. I have new coils on both sides and checked spark and both cylinder are firing strong. why won't the one cylinder fire? Any ideas would help.
