I have a John Deere LX188 with the liquid cooled Kawasaki motor. My problems seemed to start when I had the carburator replaced by a local shop. It seems that when running under a load, the mower will just quit, but not consistantly. Sometimes it will mow the whole yard, no problems. Next time out, I can't even get around the house once before it quits. I have tried several things in my troubleshooting, such as replacing the ECM, eliminated the fuel shutt-off solenoid on carb., new fuel pump twice, totally new fuel lines, cleaned the tank, cleaned the fuel cap, left the cap loose, checked for good spark, replaced the fuel filter, on and on. In my latest attempt, I bypassed the fuel tank and pump and installed a fuel nurse tank directly to the carb. Mowed for a short while, and same problem. I can throw the throttle all the way to choke, and it seems to chug and continue to run. If I don't do this, then it just shuts down. I have also tried to pour a little fuel down the air cleaner intake. It will start and run until the fuel is burned out. Sure seems like the carb is vapor-locking or a float issue, not? Had that apart and looked very clean and no issues. One other note-worthy item I noticed is that one side of the radiator is really hot, but other side is not at all. Could water pump or other issue be causing problems? I always seem to lead back to fuel. Any advice would be much appreciated.
