Small Engines (Lawn Mowers, etc.): Jon deere trs 24, jon deere, oil leaks

Question
What type of oil do I need for my TRS 24 snowblower? It is leaking oil right below the pull start how can this be fixed

Answer
Is the oil level too full and/or does the oil smell like gasoline?  If you fill the fuel tank full of gas does the fuel level stay full until the next time you use the snowblower?

Often time the carburetor will leak gas allowing gas  to mix with the oil.  Mixing the gas with oil thins the oil can and promote oil leaks.
