My Toro LX425 lawn tractor w/ a Kohler Courage 20 engine died the other day while running it, and won't restart. It turns over fine. Checked, and I have good spark. I replaced the fuel filter, thinking it might be clogged, and notice that no new fuel is flowing into the new filter (its a clear plastic housing). I think there are two possibilities:
1) Fuel line pre-filter is clogged
2) Fuel "pump" isn't drawing fuel (fuel solenoid?) through the filter. I don't know anything about power equipment fuel supply; can anyone clarify if the filter would have fuel even if the solenoid failed?
