poping flames out exhaust?

4 cylinder diesel inline injection pump tractor was left idling unattended and ran out of fuel. Now when it runs at higher RPM, it pops flames out of the exhaust. Runs ok at slower speed. What could cause this? I have never seen a problem like this before. Maybe tight exhaust valve and running out of fuel has nothing to do with problem?

I would do a valve set, change the fuel filters, and put it to work for a while if the problem persists then you can remove the exhaust manifold looking for a dead cylinder or remove the injectors and test them, and do a compression test, and or Cylinder leak down test.
It is very rare that any problem will be caused from running out of fuel.
