190C JD Lawn tractor won't start

While restarting my 190C after a short break for water, it puffed white smoke out the exhaust, then stalled, not to start again. The air filter was dirty, the spark plugs black. I changed the air filter and plugs to no avail.
I checked for spark and it was positive from both my plugs. I took the cover off the mag, the fins do not appear to be bent. Still will not start. I am running out of ideas.
I was going to check my float bowl for ant water in the gas, but cannot get to it. Appreciate any ideas.
Paul

What's it got for an engine? How was the oil level? Does it have compression?

Put your finger over each spark plug hole and crank the engine. You'll feel the compression blow past your finger if it has decent compression.

Depends on how strong your finger is, or how hard you push it. The point is to find out if it has compression or not, not how much compression. If you feel some compression, but not enough to blow past your finger, then at least it's not blown and it's time to look at the valves. If it blows past your finger, then it's time to move on to something else.
