  1. Are the top burners okay?

Great, thank you! Please allow me just a few minutes to prepare some information for you, thank you!

Expert:  Kelly replied 6 months ago.

If the top burners are okay, then all you need to do is adjust the oven orifices. If you locate the area where the burners sit over the brass orifices, you will see that there is a 1/2" wrench spot on the orifices. Turn them clockwise until they are screwed on tight and that should be very close to the appropriate flame adjustment setting. If the flames are too low, back off just a bit, a 1/4 turn at a time. If the flames are too large, tighten down more. Please let me know if you need more clarification.

I did tightened the orifice the way the install recomended
Expert:  Kelly replied 6 months ago.

If it is sooting, it is not down tight enough. You should see not threads.

a repairman looked at the flame and thinks it is a defect in the manufacture
Expert:  Kelly replied 6 months ago.

Are the orifice hoods screwed down so no threads are showing? Can you post a picture of the lower burner and valve area?
