I borrowed my dad's mower. He showed me how to start it and we started it up fine. Got it home, started it again, started fine, grass was wet so I put it in the garage. Couple days later, time to mow - won't start.

I was trying to start it in the yard - maybe the grass was too high and the blades wouldn't spin fast enough to start it? Maybe I flooded it? I've let it sit and tried again, nothing. The fuel valve is on. It's leaking some fluids and just now it was spraying fluid out of the exhaust. Seems to be seriously flooded.

What did I do and how do I fix it?

Thanks.
