I have an eleven HP Briggs Stratton on a riding mower that is getting gas in the oil. Any help would be appreciated. Thanks
Robert

Hello: Robertk

When the engine isn't running, the carb isn't fully closing off the fuel supply. The tiny amount of gas leaking thru is then entering the combustion chamber.

Check for these conditions:

A tiny amount of debris on the seat or needle. Hindge pin on the float may have restricted float movement or the float has a tiny hole in it. May have a tiny amount of debris on the seat or needle.

If the carb is a diaphram carb. The tiny needle may remain open slightly. Usually this is do to it having a hole in the diaphram or it becoming dried out. May also have a tiny amount of debris on the seat or needle.

Good Luck,
