TED spark plugs

[Véro & Fred]

Hi John.

Here's some pictures of one of the spark plugs (Champion N21) from my TED 1951.
Engine is runing with a mixture composed of 1 part petrol for one part heating oil.
Very low oil consumption.
It would be a great pleasure for me of reading your opinion concerning their color

Best regards,

Fred.

Bonsoir, Those plugs look fine to me, the colour is just what you should get when it is tuned correctly. Always difficult with a TVO type mix though.
