JD 4300 Sparks coming out the Exhaust

[jgbanshee]

I just notice tonight when the sky got dark out that my JD 4300 was shooting sparks out the exhaust. I was doing some loader work around my garage and noticed every once in a while a couple sparks shooting out with the exhaust. What is going on here?

I have had that happen on nearly every diesel I have ever owned. If you were doing a lot of loader work and the throttle was being opened and closed a lot, some unburnt fuel finds its way into the exhaust. Every now and then it will ignite and blow a little spark out the exhaust. We had an old 806 International (~100hp) that would actually stand a little flame on top of the stack on a cool night when it was really being worked hard. I would only worry if it was happening on a turbo'ed engine.
