1937 Ruby spark plug colour ?
#14
On the original subject...….

This is the colour I have on the Chummy, running a 1" SU. It's also the only Austin Seven I have had in over forty years that will do a genuine 40+ MPG!


   


I think the outside of the plug runs cooler than the electrodes, hence the black. However, the tan is pleasing to see.
