QuestionHi John, I have a John Deere 314 with a Kohler K321AQS engine spec no. 60343 . It starts right up and runs fine for about 5 minutes. Then it backfires and dies. Usually it starts right back up and runs another 5 minutes and then dies again. I've changed coils, plug wire and checked the points. I still get the same results. I really appreciate any thoughts you have. Thank you.
AnswerHello Allen:
>>Always Remove the Spark Plug Wire/s from the Spark Plug/s before Working on Any Small Engine unless the Plug/s must be Connected to the Coil/s for Diagnostic Reasons.
>>Did you Change the Capacitor when you Changed the Coil?
>>Is the Unit Moving when this Happens or Does it Matter if the Unit is Moving or Not?
>>When was the Carburetor Serviced Last? If the Float Needle Valve is Sticking, then you will have this Problem.
>>Is the Gas Free Flowing (for at Least 1 minute) to the Carburetor?
>>How Old are the Points?
>>Thanks
