Looks to me like the phone company is not a morning person like you are. :biggrin1: :biggrin1:

Bruce, I am going to need my cereal bowl back

He he I never looked at it that way!! It does look like a cereal bowl!! Probably big enough for 3 or 4 Cheerios, won’t hold milk worth beans though.


Oih, sometimes I want to throw this phone in the Harris and thrash it. Lol.

What does this thing do?

Good question, a magneto needs to have a way to protect the coil in the event that a spark plug wire falls off or breaks. They put in another place for the spark to go that has a much larger gap than the spark plugs but still close enough to spark across. On these old KW’s this device is a electrode (not shown) that goes down through this porcelain cap. Under the cap is a little button where the spark can jump to if necessary. Over time the caps crack or break or get lost.

Hope this helps

Thanks for the education.I never knew there was such a thing or that it was needed.Do modern mags have something like this or do they not need one?

I suspect they have a similar thing, just hidden inside somewhere.
