    I have an old, 4-burner Viking gas cooktop that's aways been used with propane. Of the two front burners, one is fine.

    In the past year or so, the other has started to deposit a thick layer of carbon on the bottom of cookware. What's likely to be the problem?

    Soot. The oxygen/gas ratio is off. It's burning yellow and orange, not mostly blue. Make sure the burner is free of gunk blocking the jets. You might have an adjustment screw where you can adjust the oxygen ratio, or you might have to have it serviced. Check your manual.

    No adjustment screw mentioned in the manual. I cleaned the jets as best I could, using a wire brush. It burns blue for a few seconds, then the flame grows to about 4 inches (without a pan on it) of bright yellow.

    Should be an air adjustment, sort of like on a Weber grill.

    It sounds like the air has been cut off or obstructed

    I found the old installation manual, and it does have an "air shutter" screw near the burner. Open the gap to eliminate yellow tipping, it says.

    Does that sound about right?
