New member who is retired from 40 years of construction equipment sales from Caterpillar and Komatsu dealers. Having starting problems with a JD 4120 tractor.
Well the tractor was working fine until early this week when I came to start it. It would crank but would not start. Changed the fuel filter and primed it according to the JD instructions but still could not get it to start. Removed the overflow line going back into the fuel tank and cranked the machine and had fuel coming out of it. Tried to prime it again and still no luck in starting. Hopefully someone has an answer before I have to call the JD dealer.
