Check the easy stuff first ie does it have fuel. Not to be obvious but I have been out of fuel plenty of times and cranked and cranked only to feel real dumb that I was out or the fuel shut off. Won't start without gas.
Had that same thing happen to me with one of my other machines. The spark plug boot fell apart I had to duck tape the wire to the plug just to get it back to camp.Mine died in the middle of the road hours after I got it. Loose spark plug wire.
Ok thanks for the info I'll give it a try, I haven't checked the oil since I last changed it which hasn't been long but worth a try!My bet is that the cylinder is washed down from cranking and no spark. I would pull the spark plug again and check to see if it is fuel fouled again. If it is, I would use the starting fluid to clean/dry the spark plug. Disconnect the coil and crank it over with the spark plug out. You do not want a spark available with the possibility of liquid fuel coming out of the spark plug hole. If you find any signs of liquid fuel coming out if the spark plug hole it has probably washed down the cylinder walls and now the rings are having a hard time sealing. Check the oil level and make sure that oil doesn't smell like gas. When liquid fuel is in the cylinder and washes the oil from the cylinder walls. It can now run down past the rings and over fill the oil in the crankcase. You will need to change the oil before you run the engine. Add about a teaspoon of oil in thru the spark plug hole and crank it over a little bit before you put the spark plug back in. I hope this helps. Good Luck!
