  • Trimmed some kind of lining in the boiler that was bent wrong and was contacting the flame (sorry, I forget exactly what it was)
  • Cleaned around the boiler cleanout panel
  • Checked to make sure the chimney is not blocked
  • Rechecked the first guy's work

The second technician confirmed that the odor is coming from the furnace/boiler/heating appliance. Parting words: "This should be much, much better."

Has anything been missed here?
Smoke pipe should be replaced not fixed with metal tape. Yeah you can use it as an emergency patch, but it will burn off the glue and eventually fall off. Did they leave a copy of the combustion test from a print out from a printer? Obviously there's something still wrong. You maybe getting delayed ignition, which can be from a bad nozzle, wrong nozzle, or bad igniter. It can also be from a plugged fuel line, filter, or strainer. Have you been hitting the red reset button on the primary control?
