if it is a carlin burner, ther's a good chance the end cone is coated with carbon. usual cause is too much draft, it pulls the fire away from end cone so the nasty stuff doesn't burn off like it should. very common in windy areas.

Sounds like

flame continues after burner cuts out. You'd probably be best served by contacting your oil companys service dept or someone else qualified to take a look. I think service may be in order.

Very common with 99FRD, Also need to check pump presure and angle of nozzle. Carlin's like 60 degree nozzles
