David,
We can read in the article (Ed Kazmirski, 1962):

Our Mr K Goes to Africa

Since you meet men dedicated to the same hobby and yet oceans may separate them, but the R/C language is the same and the exchange of thoughts most rampant in the ensuing “bull sessions”

Also:

Pronunciation and enunciation drew some comical statements, and laughs emanated as we compared pronunciations; such as the word solder which these men would pronounce as so-l-d-er , actually enunciation each letter.
Since the R/C individuals are of British and Dutch decent …..

We also have to communicate with German and France people that makes it all a little different for us and is for me a reason to use pictures.
You also did start this thread with:

Can anyone educate me on an OS 7D carb? It seems unusual. Thanks.

My first thought was "unusual?" than I start with basic education!
