I just found this rare primer spark plug in a old tire repair kit tube
has USA and horseshoe logo
the name under horseshoe is to small for my eyes, does anyone know any information on this plug, thank you, Bob

The only writing I see is "Trade Mark" inside the horse shoe and "Made in USA" under the horse shoe.

For ID, try these guys:

I was once told, before the internet, where all truth is to be found, that one could tell if the engine was receiving the correct air/fuel mixture by opening the petcock of a primer spark plug. A blue flame the mixture was correct. A red or yellow flame the mixture was either to rich or to lean. Now that we have the internet, any of this advice true?

Blue vs red or yellow flame is proper vs improper combustion for natural gas appliances. Never heard the same rule for gasoline engines (not saying that it isn't true, however).

The glass head Briggs in the video is burning propane. Note the Bernzomatic tank and regulator hooked up to the engine.

Interesting video. Unfortunately it was missing most of the 18 minutes. It seemed it only fired every cycle towards the end of the video when one of them started experimenting with lean and rich mixtures to see the effect on the color of the flame. That would also help to explain why it appears to have been running cooler than expected.
