An original Tv 175 series 2 6volt. Using a B6 ES spark plug. Do you think this is adequate for the job? The scooter is lightly used so not really an everyday ride. Your thought would be appreciated.

I've been told B7ES for my standard TV3

I was thinking the same 911HC.

B7 if all you are doing is pooling round town but a b8 for anything more

Now I'm confused. I thought NGK rated colder as a lower number so B8 for poodling about (hotter plug, burns more oil) B6 for hard charging and long motorway blasts for a cooler running engine. Maybe I've been wrong all these years. Quite probably!

Thanks, but no harm done, I've always used B8's.
