I have a 2 year old Toro with a Toro Labeled Motor, I think it's Briggs, 24.5 HP, v twin. I had put some gas with water in it, and obviously quickly quit running. Once I figured out the problem and drained the gas out, and put new fresh gas in, the engine has one cylinder dead. The plug is very wet and not firing. Lots of blue smoke coming out of engine, I've swapped plugs, then coil, adjusted valves, removed the kill switch wires, problem persists in the same cylinder, I followed up with compression test, which was slightly over 100 for each cylinder. It runs with the bad cylinder plug wire off, but not with the good cylinder off. I've read some people have had similar problems and changed carburetor and it fixed it. I really can't see the carburetor being the problem, this doesn't have many hours on it. Any suggestions on what I might check?
