A couple of years ago when the engine quit, I re-powered my 6x4 Gator with a twin cylinder 22hp Predator. My brother repowred his splitter with one years ago and has had good luck with it ( other than hard starting in cold weather due primarily to the carburator being tuned to meet Kalifornia regulations) so it seemed like a good alternative. I have had ongoing issues with the float valve sticking and it dumping gasoline into the base. Turns out that many of the neighboring Amish use these 2 cylinder engines as well and most have told me that they have the same problem. The issue appears to be a design or manufacturing flaw. It isn't that the valve itself sticks but that there isn't enough clearance between the float and the bowl; the float hangs up on the housing. Anyone else out there with this problem (or a solution).
