spark plugs

[single speed]

a friend of mine has a 1925 morris bullnose, and is having trouble getting plugs for it. they need to be 19mm thread, with a thread length of 19mm. does anyone know of a supplier?

Hello

When it left the factory, it would have had 18mm plugs and unless someone's been mucking about, I suspect it still has.

The correct length for a bullnose Morris 11.9 or 13.9 (or even a later flatnose) have been unobtainable for years, but a compromise will do and its worth contacting the Greens spark plug Company:

Try NGK A-6 plugs. If all else fails, you might have to use a plug bush.
