pull the plug and put your finger over the hole and spin it over to see if its got compression and if not pull the head and check to make sure the valves are working and see if they are closing all the way just a small gap will make it not run

the gas in to the oil sounds like the needle valve in the carb is not seating right and allowing gas to go in to the combustion chamber
