John Deere X500 Backfires at Low RPM
Hello, I have a John Deere X500 that is hard to start and is backfiring at anything below half throttle. When it does start, it runs great at full throttle but when I engage the blades it doesn’t have enough power and bogs out. Lower throttle it back fires and wants to die. I have good fuel flow, fresh fuel, new plugs with good spark. Could this be a carburetor issue or is it likely to be valve train related?
Thanks for reading!
