A search on the lawn mower forum proved to be a valuable tool in the repair of my B&S small engine. I discovered what to look for while troubleshooting my problem and it was right on. Without a doubt I'll be using the forum in the future. The needle valve seat on my carburetor was damaged letting fuel to pour out of the carburetor intake. The engine is only four years old but it seem that 10% ethanol fuel will not help small engines.
