Brigs & Stra 14.5 hp, got gas in oil.
Mower had been running great. Month later started, lots of smoke, then blew oil out breather. Removed filter, full of oil, checked oil level, way overfull. Drained gas/oil from crankcase. Suppose float stuck or float needle valve stuck. Drained gas tank.
Question: What is the purpose of the solenoid on the bottom of the carburetor bowl?
