I have a shitty craftsman push lawnmower with a Kohler xt675 engine. it was a gift from the in laws so i had to keep it, but thats another story. Anyways for 3 years its started every time the first pull and i go to cut grass for the last time the other day and the fricker won't start. I figured it was the spark plug b/c it sounded like it wasn't getting any fire, so i changed it. didn't work. the air filter is clean and the gas is good. the lines look like they are okay. it just sounds like its not turning over. oh and the oil was changed in the spring.
Any ideas as to why it may not be starting? I just want it to crank one more time

i'm going to spend a little cash on one next spring.... probably get the honda, but i don't want to buy one right now just to put it up for 4 months or so.

I know you said you changed the plug, but did you verify that it was indeed sparking?

If you leave ethanol fuel in carb it corrodes the fuel solenoid switch on bottom of carb.

On Kohler it's typically near the muffler.
It is the part on the bottom of carb with wires going to it. The carb typical Nikki or walbro carb and just make sure get right solenoid if you have to replace it. Nikki will have Nikki on the carb.

It has wires going to it and it's job is to shut off fuel flow when engine off so you don't have fuel all over the place.

Make sure engine and muffler not hot due to when take fuel solenoid out fuel will pour on the muffler and heat and fuel don't mix. Try to use a funnel to reduce fuel leakage.
1. Unhook wires
2. Unscrew fuel solenoid
3. Clean with carb cleaner the spring under the metal
4. If carb cleaner works and metal piece goes up and down freely put back in.
5. If not replace with new one and reverse steps

99% of the times this should help if engine turns but sound like not getting fuel.

If not turning check
1. Battery should be 12 volts with meter
2. Check to see if solenoid getting juice they stick it's nature of the beast and cheap fix
3. If that working then check seat safety switch, if rider has another safety switch by the brake, and zero turn its by lap bars.
