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.
First thing. Did you check to see if the engine is clean with no buildup
on the fins? Is the engine running faster than it was originally governed?
It sounds like it might be getting too hot. Also synthetic oil helps air
cooled engines run a little cooler as well as longer life.
