Take the muffler back off and inspect the exaust side of the cylinder and the piston for scoring, If you have any he most likley ran it with the wrong oil or no oil in the gas. also check if the plug is wet when after you try to start it w/ the choke on.
Yes, when I first pulled the heavily fouled plug it was wet from fuel and every time you would crank it with plug removed it would spray fuel.
I will check it again in the AM to see if it is still spraying. I even removed the fuel screen and just left the pickup tube in the cleaned out tank with fresh fuel.
