Hi Everyone, I apologize in advance for asking this question as i'm sure it's been asked many times. What is the modern equivalent of a KLG F70. I have been running a NGK B7HS in my WM20 without problems, but it would be nice to know for sure. Thanks Mike.

iron head L86C or NGK B6HS
Alloy head N5C or NGK B6ES

but no guarantees that I have it right! Ian will tell us in an instant..

Very interesting, Could you tell me what make the L86C is and weather the B6HS is hotter or colder than the B7HS. Cheers Mike.

With NGK, the higher the number the colder the plug.
Most are like that except Bosch....... and maybe all others

L86 is a Champion

Have a shufti at the Green Spark Plug Co site, lots of info

And don't forget to gap any plug to .018"-.020" for magneto applications and use a 'non suppressed' plug cap...Ian
