I've got a 23 HP diesel Kioti tractor, 3 years old. As I was operating the backhoe at about 1/2 throttle, the engine suddenly over revved, smoked for less than 10 seconds and then died. I checked all fluids, temps, etc looked over the engine for any obvious problem and all was fine. To my surprise, it started right up and ran fine for the rest of the job.
The next time I used it, it happened again, this time when I was trying to make it happen by operating the throttle from idle to fast and back a few times in rapid movements.
The only thing that was a little different is I had filled the fuel tank that was near empty with fuel that had been in the fuel can over the winter.
Can anybody tell we what could be happening and what my next step should be?
Thanks.
