Re: Fuel in oil - where to start?
I had a similar issue with my riding mower. Apparently, it is common on mowers. I got a rebuild kit and replaced the gaskets and seats. The float would not close the fuel off when the engine was not running and the bowl would fill and overflow into the cylinder. The local mower store told if the rebuild kit didn't fix it, a fuel shut off vale would do the trick. In my case, the kit worked.
