Question about Troy Bilt 5.5hp Self Propelled Mower
If by fouled you mean the plug tip is wet with oil (you would also get a lot of smoke while it's running), the cylinder or rings are damaged and oil is getting by the piston. If the plug is dry and has lots of black soot on it, it's running too rich for your altitude. Most lawn mowers are set to run at about 1000 feet of altitude to work in most areas. If you are well above that your air is thinner and the carb will run rich. Depending on the type of carb you have, you have to adjust the fuel flow needle valve or get smaller jets to meter the gas through the carb.

Hi , it can often be something as simple as the engine needing a oil change as oil looses viscosity/thins with use ( use correct grade ), replace or clean the oil filter and a good service or something more complex which requires a full engine stripdown like worn piston ring/oil scraper ring causing oil to flow up the cylinder walls and fouling the combustion chamber or oil leaking up through the valve stem oil seals , also storing the machine tilted can cause oil to collect in the chamber or petrol to leak into the sump causing the oil to thin.
Hope this helps , please rate accordingly
