Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you. Remove your spark plug, and insert about 12 inches of soft rope, into your spark plug hole. The rope will serve as a piston stop, to prevent your crankshaft from rotating, as you are attempting to loosen the nut.
Make sure your piston is about mid-ways down inside your cylinder, prior to inserting your rope. A piece of pull rope from a lawnmower, or trimmer, etc. will work well for this purpose.
You and I can continue from here. Thanks!
