The problem seems to have healed itself. I took a rag to the air cleaner, wiped up the spill below the carb, and drove the hell out of it all week without any incident. still have a wee bit of oil coming out of the oil tank cap even though I put a new rubber gasket (cone shaped with hole in middle). Need to solve that problem. From now on I will have someone start it monthly believing that will prevent sumping again in the future.
If anyone believes I should have drained all the oil or done something else, by all means say so. Thanks in advance.
