Need some help with the choice of the sparkplugs.
Got some NGK which runs great.
Didn't found them in the Internet
For me is the reading M76f?
Run them on 350 with 10:1
Any recommendations about a different one?
NGK's are excellent and you have a specific recommendation from an experienced professional...I'd go with Mark's suggestion of XR5. Pull them in a few hundred miles and see how they look.
