    There is no seal. Instead, they used a slinger to throw the oil off the shaft. It is then sucked back down to the carburetor for recycling.
    Look for a badly worn crankshaft bearing. Or an obstruction in the return passage to the carb. It can be seen by removing the carb. It is a small hole at the top of the carb gasket.
