I've got a Toro LX425 w/ a Kohler Courage 20 engine (SV600 series). I was in the middle of mowing the other day when it stalled and wouldn't restart. It cranks fine, just won't start.
I pulled the plug, and have good spark (replaced the plug just in case). I then replaced the fuel filter, and verfied I have fuel all the way to the carb (Walbro single barrel).
I pulled the fuel shut off solenoid, and tried turning the ignition on/off with this uninstalled. The plunger was not moving, and was stuck in the "extended" position (which I assume is shutting off the fuel supply). Assuming this was the problem, I first tried soaking it in carb cleaner with no luck. I then pushed the plunger back down (to the fuel "on" position) and reinstalled it, thinking that if it wasn't moving, with it stuck in the "on" position the mower should start. Still nothing. I removed it one more time to make sure it was still "on", and it was.
Lastly, I dumped about 1 teaspoon of gas directly into the spark plug hole, reinstalled the plug, and tried it. Still nothing.
I am stumped now. How can it not tempoarily start, when I have spark and have manually added fuel? Wouldn't any other catestrophic damage be obvious?
