Anyone experienced over heating issues?
Kohler engine runs great for about 20 minutes and then boggs down.
Had to replace oil pan because ears broke off. Also replaced cam because i broke the neoprene cam gear.

Are you sure it is overheating and not an ignition module that is failing when it gets hot, resulting in running on one cylinder. Also did you get the timing marks lined up correctly between the cam and the crankshaft. I don't think I have ever seen the mounting ears break off of the oil pan excluding impact with a solid object. And how did you break the camshaft gear.

Have you ever cleaned the cylinder cooling fins, all the way around the cylinder? It's a yearly maintenance thing in your engine manual. Ignore it and you are looking at engine damage.

In early spring if you scalp the yard, good idea to clean the cooling fins after scalping. If you have a bagger you need to check and clean more often.
