please dont just shoot me, but am seeing a lot about a knock in the old single Kohlers. do you really have an issue or is it just the Kohler knock? an old warranty rep years ago said to widen the gap on the plug, if it starts going away, you can either leave it there or bring it back. if you have the widen gap, you will loose some power. just a thought.
