Old furnace ok to run?

[Plumber69]

3 of the burner tubes have a flame like this before the flame spreader. Is this a big issue?

Looks like a pilot light? A model number, etc. would help with a lighter exposure and more of the burner.

Pilot light is ahead of the flame spreader. These 3 other flames are before the flame spreader

If you put this furnace in your house it would behoove you put in a CO detector nobody needs to die from carbon monoxide even if you get it checked out.
