Hello, I have a Wheel Horse 656 that I repowered with a 6-1/4hp Kohler K141T that was originally on a log splitter. I've been having an issue with it shutting down when it gets hot. It shuts completely off like the key was turned off, although this engine is a pull start. It will start back up and only run on low idle. It will start up and run normal when cooled down. I originally thought it was the ignition and replaced the coil and condenser with new OEM parts and it still does it. I don't believe it's the fuel either because it pumps fuel, has new fuel line, OEM filter and new shut off valve with the screen. I then took out the valves and cleaned them up and ran a 5/16" reamer down the valve guides thinking that the exhaust valve may be sticking when it gets hot. So far nothing I've tried has worked. I'm curious if maybe I'm just working it too hard. The mower has a 35" cut and I mow a lot in top gear up inclines and it's been pretty hot out. The engine is within the wear limits internally, has plenty of power and doesn't smoke or knock. It's set to about 3,500rpm at full throttle with no load. Any opinions or suggestions on what might be wrong or where to go from here? Thanks, Tim
