My Cub Cadet with Kohler engine runs for about an hour then quits. The engine seems quite warm when I raise the hood. It won't start again until it has cooled off for at least 2-3 hrs.. Does the engine have a high temp cut-off?

No high temp cutoff. what engine do you have. It would be easier to identify the problem if we knew the model of engine in your cub.

Could be that the ignition coil is on its way out.
When the engine shroud is in place there should be a strong flow of air flowing down across the cooling fins of the head(s) and spark plug area. Being careful of where you place your hand around moving pulleys etc. and hot exhaust, you should be able to feel that air flow. If you can't feel a good air flow it may be time to remove the shroud and check for a rodent nest blockage. That's one of their favorite nesting locations.
Thanks for all the replies. I did notice that the air inlets in the shroud weren't building up debris like they normally do. So I wondered if the fan had stopped. I looked closely behind the engine to see the fan and found (difficulty to see) that the inlet screen in front of the fan was mostly clogged with grass clippings. I cleaned it off and did more mowing and the engine was markedly cooler afterwards. I think I have found the problem and hopefully fixed it. Thanks again.:smile:

Well if you have, then clean it more often then the problem will not return....:thumbsup:
Right on. It would help if the screen was more visible, but it is what it is.

spark plug gap's for Kohler engine's are from .025" to .035" Champion recommend .025"
