I need HELP. I have a Husqvarna 21 HP Kohler 46" lawn tractor. It will NOT start. Battery is fully charged, spark plug is good, oil is fine, air filter is fine and the solenoid is fine. I have one more thing to check (fuel filter) but I don't have a good feeling. Any idea what the problem is or might be? The engine doesn't even sound like it wants to turn over. It's only 1 1/2 yrs old. This is ridiculous. :dunno:
