I have a Toro 16hp riding lawnmower. I am getting gasoline in the oil. I pulled the carb and cleaned it out thinking the float wasn't seating right. But that didn't fix it. I put an inline shut off valve. But since I suffer from CRS, when I went to cut the lawn this weekend I found I didn't shut it off. I checked the oil and yep it was full of gas. When I drained it, it filled a 2 liter soda bottle. What else can I do?
