Any clue as to how gas is getting into the oil - considering it has an electric fuel pump?! Not sure what else to look for?
carb leaking,clogged air filter,choke stuck on,vacuum line broken/unhooked/clogged...does it take a lot of cranking to start ?..any of the above can cause fuel in the oil...although there is always going to be a tiny bit that will leak by the rings especially with a carburated engine
