I have a pull start 10.5 HP Briggs & Straton vertical shaft engine on a DR brush mower that got flooded probably when the float bowl malfunctioned (kept filling with gas until over a quart of gas got into the crankcase) and fortunately I found out what had happened before I tried to start it. I drained the crankcase, removed the spark plug then slowly pulled the pull starter until all the gas in the combustion chamber was out. Next I filled the crankcase with new engine oil, squirted oil in through the spark plug hole and pulled the pull starter a number of times. I'll change the oil again remove the muffler and clean it out before trying to start it. As a more permanent solution I plan on adding an in line fuel filter, it already has a fuel petcock anything I've overlooked ?
