Welcome to JUST ANSWER small engines, let me try to help you !! Model number? Single cylinder or twin. Most likely is the sump to the block gasket, It shows up when engine is running. Repair requires the sump be removed and new gasket installed. The gasket get washed out over time from the oil being splashed on it.
