Here is another old trick. take the plug out, bring the piston up to tdc and, then pull on the rope until the piston is half way down. Without going pass the exhaust port.
Take a tea spoon of straight mix oil and pour it in the cylinder, let it sit for half an hour so that the oil will soak down around the piston and behind the rings.
Now this is the important part
Take a shop rag or paper towel, with out blocking the spark plug hole cover it, turn it on it's side, give it a hard pull and get the extra oil out of the cylinder. (switch off)
Once this is done, put a new gaped plug
in and see if it will start. If it does, it will smoke really badly. Run it at WOT until the smoke/oil burns out of the muffler.
If this dosen't work, the only other thing I can think of is replace the rings with new, if you havn't already. As long as the cylinder is not scored. Any scratches, no matter how small, and it will never run.
