I'm new here so please excuse any mistakes. I have a JD jx 75 walk-behind and it's only 4 years old. It's been fine all summer but yesterday it was running a little rough and my son shut it down. We haven't been able to get it started since. It seems like it wants to crank but it just won't catch. I thought it might be flooded initially. I take good care of things and winterize etc. properly. I changed the spark and put fresh gas in but still have no luck. My guess is there may be water in the fuel from all the humidity this summer. Any expert opinions welcome.

It has the Kawasaki engine.

Regards,
Cary

Isn't there anyone out there with some small engine experience? I'd just like a suggestion or 2 please. Once again, this is a John Deere JX75 walk behind mower with the Kawasaki engine and it won't start for some reason.
I'd rather try a couple things before paying $60 an hour for dealer work.

Respectfully,
Cary
