I have a 345 lawn tractor, only 700 hours. Have replaced fuel filter, fuel lines, cleaned carb, new plugs, air filter. Cleaned gas tank. Problem is runs about 90 minutes then stops, rests a while then goes at it again. Today will not run more than a few minutes. Read something about coil going bad. What coil would that be. Thanks
Make: John deere
Hi, and thank you for letting me try and assist you with your problem.That coil would be the ignition coil.The part number from John Deere is AM120732 and it sells for $57.00What you can do to verify that's the problem is get yourself an inline spark tester that looks like this.It goes between the spark plug and the spark plug wire.If you have spark it flashes orange.Plug it in, run the motor and see if it stops flashing when it dies. If it does I'd look into a new coil.
