did he remove the the burner at all? inspect the combustion chamber and heat exechanger?
whats this about an oil pump? has he had a pressure gauge on it?
has he set the combustion correctly.
or are you in the position still of him standing there using his xray vision to diagnose whats going on inside.
from experience i would say that burner head is covered in carbon.
