Your tractor may not be starting due to an electrical fault. If your tractor turns off on the key instead of on a pull cord it could be the electrical shut off on the pump. On the pump you will see a wire going to a big nut, undo the nut, there will be a plunger type pistern, remove this, if the tractor starts you have an electrical fault where the pistern is not moving up and down from the key. Basically when you turn the key off the little pistern goes down and stops the fuel. Hope this helps. Regards, Rich
