I have a 10 year old Poulin Pro that has a Kohler engine. The
symptoms of my problem are simple. After the mower has sat overnight,
it is easy to start. Even if I run it only a short time, it is easy
to start. However, if I run it for an hour or two and shut it down, I
may not be able to start it back up. It appears that the problem
occurs only if the engine has been run an extensive amount of time and
then shut down. In that case, it won't start until I let it sit
overnight. What is going on? Any advice will be appreciated.

In order for an engine to run, you need 3 things. You need
air, fuel, and spark. You need to determine which of these
three things is missing, then troubleshoot that system.

Well, that's certainly true -- but his symptoms point to exactly *one* of
those three things: spark. I'm betting he has a bad magneto, and it's failing
when it gets too hot.

The engine never stops after it is running. The only time it will not
start is after it has been run for a long time(1-2hr). If the
magneto was failing when it gets hot, wouldn't it stop running?

Not necessarily -- if 'running' implies 'moving', the magneto could actually
be cooler while running than while shut off and parked for a while after
having been run for an hour.
What happens if you run it long enough to get it good and hot, then park it
with the engine running?
