Hey welcome to the world of oil burner service!! :-) Theyare a finnicky beast to say the least. The problem you are having sounds like an air mixture problem. A combustion analyser would be the best tool to have but being that you probably don't have that try this. On the left side of the burner as you are looking at it is an air adjust ment ring and a fine tuning ring. the fine tuning ring is probably all you need to adjust. There is a screw that is usually right behind or near the pipe coming out of the pump and going into the burner. Loosen that and turn the ring away from you just a bit to close off some of the air and you will be fine. The burner is running a bit to lean. If you can see the flame turn the adjustment closed just until the flame color turns from a almost white color to a slightly orange color. Then you should be fine. Good luck!!

Sure can. To do it properly, you should perform a smoke test after each adjustment. This requires a special tool. This may be why noone has answered your question yet. There is a band on the left side of the burner that can be opened to allow more air in. The flame should be bright orange/yellow. And again, perform a smoke test after you adjust it.

No, you should call a person that can service oil burners. Either the nozzle is bad and oil is dripping into the burner tube and running down or the nozzle is loose and the oil is running out from the threads of the nozzle. Either way the nozzle should be changed and the burner retuned with a combustion analyser..

As you face the burner, mounted in the unit, the oil line feed in on the left side. There is a cap, held on by 4 7/16" bolts. Inder the cap, there is a screen. You would be best to get a screen kit, available from the same place you get your nozzle, as it will come with a new gasket.
Shut off the oil. Remove the four bolts, pull the old screen, clean the housing (I use rags and WD40) and re-asssemble. If is is really bad, you should remove the nozzle assembley and flush the oil line to the nozzle, as well.
THe oil filter, screen and nozzle should be replaced at least once a year.
