Kohler rocker arm issues
 

I have a Cub I bought in 2014. It has 210 hours and the rocker assembly in both cylinders went bad. Has anyone else had this problem. Is this something common to Kohler 2 cylinder horizontal shaft engines? I bought w Cub with the Kohler because Kohler is supposed to be the best. Did I make a big mistake?

What model tractor??
"Cub Cadet with a two cylinder motor" isn't very specific...

Yes, some of the Kohler engines had rocker issues. Usually you fix them and it isn't an issue anymore. They are still a good engine. I will say, usually rockers make noise when they start to get loose. How long did you run it with it clattering?

What Kohler engine does it have? The Kohler commands are great engines but the Kohler courage are a POS and known to have multiple issue including the valves.

In order to answer your question we need to know what model tractor you have and what engine it has. :bigthink:
