Question Toro Wheel Horse Kawasaki Cuts out

Hi there. I have a Toro Wheel Horse with a Kawasaki liquid-coold V-Twin OHD, FD620D. The issue is engine will runfor a random period (sometimes for 600mins, though increasingly for less time, eg 5mins) before cutting out. I cannot restart it immediately: by using choke (even though hot), it may cough and splutter but then dies out with eventually no response to ignition turning engine over (ie will not fire). I have to leave it for a while before I can restart it and off we go again... I have removed sparkplugs and checked that there is a spark when engine dies, so does not seem electrical. Have thoroughly cleaned carb and have replaced fuel filter. Anyone have any ideas? Thanks

I just worked on one of these engines that had the same symptoms you described, I went through EVERYTHING !!!

After taking a step back, I hooked a gravity feed tank (old Honda gas tank) to it and it ran like a champ. Problem was the fuel pump, It would intermittently stop pumping fuel.

That explained the varying run/re-start times, A new pump got it out of my hair.


Good Luck

Funny, I was about to mention the same thing. I have a deere lx188 with that engine and it does the same thing at times. I discovered it was the fuel pump as well.

Check the fuel lines for internal deterioration. I have seen many of fuel lines damaged from ethanol fuel. The fuel line from the tank to the fuel pump has been the one I find damaged. I replace them all with ethanol resistant line.
