John Deere - Motor Failure in First 28 Hrs. of Operation
DES MOINS -- At about 28, hours the motor on my D110, purchased from Home Depot started to run rough and backfire through the carburetor. I turned the motor over by hand with the spark plug out and my finger over the hole. I could not feel any "intake" stroke. I removed the valve cover. The stud for the intake valve had come loose. There was evidence of lock-tite on the stud but it did not look like it had set properly. I suspect they may have more of these problems coming. Not too bad if you understand small motors and have the tools but it will be a pain to the average lawn "mower"
