wheeledhorseman 573 #2 Posted June 26, 2013 Do you have a magneto ignition i.e no battery or conventional 12 volt ignition coil? If so I guess the problem lies in the 'kill' wiring. To stop a magneto ignition engine the points are effectively short circuited to prevent any further sparks at the spark plug. On Kohler K engines this was achieved either by a 'stop' button on the points cover or a wire leading from the points to the ignition switch in which case when the switch is in the off / stop position the wire is effectively grounded either through the casing of the switch or via a tab connector which is visibly connected to the switch casing. I have had ignition switches play up and not ground the kill wire or the fault could be in the wiring. Hope this helps a little. Sorry I can't be more specific but you havent mentioned the WH model or 'spec' for the Kohler engine. Andy Share this post Link to post Share on other sites
Lane Ranger 10,488 #3 Posted June 26, 2013 Andy: Describes it well but having a Kohler 7HP is a dream motor! Is it recoil star or electric with a battery and key switch? Share this post Link to post Share on other sites

wheeledhorseman 573 #5 Posted June 26, 2013 'Dieseling' or 'pinking' after turning an engine off and where it tries to continue to run is usually associated with glowing carbon material in the combustion chamber i.e the head needs decarbonising. Share this post Link to post Share on other sites

Also check and make sure you are at idle when you shut it down, it should idle a little less than 1000rpm Share this post Link to post Share on other sites
