1961 220Sb spark plugs
« on: October 03, 2021, 17:55:46 »
My 220Sb uses oil and fouls the plugs.  Is there a hotter plug that could be used to make them last a little longer?  I currently have the W7DC Bosch spark plugs in it.

I think NGK B5ES.
Certainly Bosch W8 or W9 - but I have never spotted any...

Thanks, I'll try the NGK.  I think I used W8 back in the 1990s.  I haven't seen them either.
