My 580 hr. 2003 Kohler 20hp V-Twin has a knock at idle.
I hear it when I am done mowing, and waiting for her to idle down... so shut down will be ok.
It still runs on, even after idling for 3 minutes or so.
Should I run mid grade fuel in it ?
At full throttle and mowing through heavy grass tonight...
it does not Knock , and runs very smooth.
Is this a rod bearing... or something else.
