My JD 425 with 1900 hours started acting up this summer. It will quit or start to sputter and miss. If it quits it is hard to start sometime not firing or it will backfire. By the way these things will run backwards. Which can't be good for it. It is happening more often now.
I put steel cam in it around 1200 hr so it shouldn't be timing issue.
I haven't checked the plugs, where replaced with cam. As the problem comes and goes I don't think its the plugs. I think its an electrical component that is getting week.
Any thoughts on this?
