Per the Kohler K series service manual, idle speed is 1200rpm, max 1500.

Thanks Bill but kohler manual also says idle speed may depend on equipment. Mine is at 1050 now. I like the way it sounds at that speed, 1200 sounds like a lawn mower!

My concern is the compression release happens below a set speed and centrifugal force turns it off as speed increases. Cooling is also a concern.

Main thing is to keep enough air moving around the engine to keep it from over heating.

I've always figured that it had more to do with the oil dipper flinging enough oil at low speed.

Had thought of that. I set it at 1200 b/c that is recommended. 900rpm does sound cool though!

I'm guilty of having a too low idle on a couple machines for that exact reason.

 

I once seized a main bearing on a 6cyl industrial engine turning about 200 rpm. Lesson learned.
